 The `name()` method should return the name of the effect which is
 used by the set and change effect blocks, for example `ghost` or `fisheye`.
 
-The `apply()` method is used to apply the effect on a bitmap. The bitmap
-can be accessed using the `bitmap` parameter and is writable.

 # Registering the graphics effect
 To register the graphics effect, use \link libscratchcpp::ScratchConfiguration::registerGraphicsEffect() ScratchConfiguration::registerGraphicsEffect() \endlink.
 
 ```cpp
 libscratchcpp::ScratchConfiguration::registerGraphicsEffect(std::make_shared<MyGraphicsEffect>());
 ```

+# Why should effects be registered?
+Effects in Scratch are usually identified by their name (`ghost`, `brightness`, etc.), but this isn't effective
+when it comes to running projects. Those "names" are therefore replaced by \link libscratchcpp::IGraphicsEffect IGraphicsEffect \endlink
+pointers which makes working with effects faster.

+        resampling.
+
+        To reproduce this problem, open the "plug:dmix" device, and set the sample rate to 44100. Internally, it looks like dmix uses a
+        sample rate of 48000. The hardware parameters will get set correctly with no errors, but it looks like the 44100 -> 48000 resampling
+        doesn't work properly - but only with MMAP access mode. You will notice skipping/crackling in the audio, and it'll run at a slightly
+        faster rate.
+
+        miniaudio has built-in support for sample rate conversion (albeit low quality at the moment), so disabling resampling should be fine
+        for us. The only problem is that it won't be taking advantage of any kind of hardware-accelerated resampling and it won't be very
+        good quality until I get a chance to improve the quality of miniaudio's software sample rate conversion.
+
+        I don't currently know if the dmix plugin is the only one with this error. Indeed, this is the only one I've been able to reproduce
+        this error with. In the future, we may want to restrict the disabling of resampling to only known bad plugins.

+PulseAudio Backend

+#ifdef MA_HAS_PULSEAUDIO
+/*
+The PulseAudio API, along with Apple's Core Audio, is the worst of the maintream audio APIs. This is a brief description of what's going on
+in the PulseAudio backend. I apologize if this gets a bit ranty for your liking - you might want to skip this discussion.
+
+PulseAudio has something they call the "Simple API", which unfortunately isn't suitable for miniaudio. I've not seen anywhere where it
+allows you to enumerate over devices, nor does it seem to support the ability to stop and start streams. Looking at the documentation, it
+appears as though the stream is constantly running and you prevent sound from being emitted or captured by simply not calling the read or
+write functions. This is not a professional solution as it would be much better to *actually* stop the underlying stream. Perhaps the
+simple API has some smarts to do this automatically, but I'm not sure. Another limitation with the simple API is that it seems inefficient
+when you want to have multiple streams to a single context. For these reasons, miniaudio is not using the simple API.
+
+Since we're not using the simple API, we're left with the asynchronous API as our only other option. And boy, is this where it starts to
+get fun, and I don't mean that in a good way...
+
+The problems start with the very name of the API - "asynchronous". Yes, this is an asynchronous oriented API which means your commands
+don't immediately take effect. You instead need to issue your commands, and then wait for them to complete. The waiting mechanism is
+enabled through the use of a "main loop". In the asychronous API you cannot get away from the main loop, and the main loop is where almost
+all of PulseAudio's problems stem from.
+
+When you first initialize PulseAudio you need an object referred to as "main loop". You can implement this yourself by defining your own
+vtable, but it's much easier to just use one of the built-in main loop implementations. There's two generic implementations called
+pa_mainloop and pa_threaded_mainloop, and another implementation specific to GLib called pa_glib_mainloop. We're using pa_threaded_mainloop
+because it simplifies management of the worker thread. The idea of the main loop object is pretty self explanatory - you're supposed to use
+it to implement a worker thread which runs in a loop. The main loop is where operations are actually executed.
+
+To initialize the main loop, you just use `pa_threaded_mainloop_new()`. This is the first function you'll call. You can then get a pointer
+to the vtable with `pa_threaded_mainloop_get_api()` (the main loop vtable is called `pa_mainloop_api`). Again, you can bypass the threaded
+main loop object entirely and just implement `pa_mainloop_api` directly, but there's no need for it unless you're doing something extremely
+specialized such as if you want to integrate it into your application's existing main loop infrastructure.
+
+(EDIT 2021-01-26: miniaudio is no longer using `pa_threaded_mainloop` due to this issue: https://github.com/mackron/miniaudio/issues/262.
+It is now using `pa_mainloop` which turns out to be a simpler solution anyway. The rest of this rant still applies, however.)
+
+Once you have your main loop vtable (the `pa_mainloop_api` object) you can create the PulseAudio context. This is very similar to
+miniaudio's context and they map to each other quite well. You have one context to many streams, which is basically the same as miniaudio's
+one `ma_context` to many `ma_device`s. Here's where it starts to get annoying, however. When you first create the PulseAudio context, which
+is done with `pa_context_new()`, it's not actually connected to anything. When you connect, you call `pa_context_connect()`. However, if
+you remember, PulseAudio is an asynchronous API. That means you cannot just assume the context is connected after `pa_context_context()`
+has returned. You instead need to wait for it to connect. To do this, you need to either wait for a callback to get fired, which you can
+set with `pa_context_set_state_callback()`, or you can continuously poll the context's state. Either way, you need to run this in a loop.
+All objects from here out are created from the context, and, I believe, you can't be creating these objects until the context is connected.
+This waiting loop is therefore unavoidable. In order for the waiting to ever complete, however, the main loop needs to be running. Before
+attempting to connect the context, the main loop needs to be started with `pa_threaded_mainloop_start()`.
+
+The reason for this asynchronous design is to support cases where you're connecting to a remote server, say through a local network or an
+internet connection. However, the *VAST* majority of cases don't involve this at all - they just connect to a local "server" running on the
+host machine. The fact that this would be the default rather than making `pa_context_connect()` synchronous tends to boggle the mind.
+
+Once the context has been created and connected you can start creating a stream. A PulseAudio stream is analogous to miniaudio's device.
+The initialization of a stream is fairly standard - you configure some attributes (analogous to miniaudio's device config) and then call
+`pa_stream_new()` to actually create it. Here is where we start to get into "operations". When configuring the stream, you can get
+information about the source (such as sample format, sample rate, etc.), however it's not synchronous. Instead, a `pa_operation` object
+is returned from `pa_context_get_source_info_by_name()` (capture) or `pa_context_get_sink_info_by_name()` (playback). Then, you need to
+run a loop (again!) to wait for the operation to complete which you can determine via a callback or polling, just like we did with the
+context. Then, as an added bonus, you need to decrement the reference counter of the `pa_operation` object to ensure memory is cleaned up.
+All of that just to retrieve basic information about a device!
+
+Once the basic information about the device has been retrieved, miniaudio can now create the stream with `ma_stream_new()`. Like the
+context, this needs to be connected. But we need to be careful here, because we're now about to introduce one of the most horrific design
+choices in PulseAudio.
+
+PulseAudio allows you to specify a callback that is fired when data can be written to or read from a stream. The language is important here
+because PulseAudio takes it literally, specifically the "can be". You would think these callbacks would be appropriate as the place for
+writing and reading data to and from the stream, and that would be right, except when it's not. When you initialize the stream, you can
+set a flag that tells PulseAudio to not start the stream automatically. This is required because miniaudio does not auto-start devices
+straight after initialization - you need to call `ma_device_start()` manually. The problem is that even when this flag is specified,
+PulseAudio will immediately fire it's write or read callback. This is *technically* correct (based on the wording in the documentation)
+because indeed, data *can* be written at this point. The problem is that it's not *practical*. It makes sense that the write/read callback
+would be where a program will want to write or read data to or from the stream, but when it's called before the application has even
+requested that the stream be started, it's just not practical because the program probably isn't ready for any kind of data delivery at
+that point (it may still need to load files or whatnot). Instead, this callback should only be fired when the application requests the
+stream be started which is how it works with literally *every* other callback-based audio API. Since miniaudio forbids firing of the data
+callback until the device has been started (as it should be with *all* callback based APIs), logic needs to be added to ensure miniaudio
+doesn't just blindly fire the application-defined data callback from within the PulseAudio callback before the stream has actually been
+started. The device state is used for this - if the state is anything other than `ma_device_state_starting` or `ma_device_state_started`, the main data
+callback is not fired.
+
+This, unfortunately, is not the end of the problems with the PulseAudio write callback. Any normal callback based audio API will
+continuously fire the callback at regular intervals based on the size of the internal buffer. This will only ever be fired when the device
+is running, and will be fired regardless of whether or not the user actually wrote anything to the device/stream. This not the case in
+PulseAudio. In PulseAudio, the data callback will *only* be called if you wrote something to it previously. That means, if you don't call
+`pa_stream_write()`, the callback will not get fired. On the surface you wouldn't think this would matter because you should be always
+writing data, and if you don't have anything to write, just write silence. That's fine until you want to drain the stream. You see, if
+you're continuously writing data to the stream, the stream will never get drained! That means in order to drain the stream, you need to
+*not* write data to it! But remember, when you don't write data to the stream, the callback won't get fired again! Why is draining
+important? Because that's how we've defined stopping to work in miniaudio. In miniaudio, stopping the device requires it to be drained
+before returning from ma_device_stop(). So we've stopped the device, which requires us to drain, but draining requires us to *not* write
+data to the stream (or else it won't ever complete draining), but not writing to the stream means the callback won't get fired again!
+
+This becomes a problem when stopping and then restarting the device. When the device is stopped, it's drained, which requires us to *not*
+write anything to the stream. But then, since we didn't write anything to it, the write callback will *never* get called again if we just
+resume the stream naively. This means that starting the stream requires us to write data to the stream from outside the callback. This
+disconnect is something PulseAudio has got seriously wrong - there should only ever be a single source of data delivery, that being the
+callback. (I have tried using `pa_stream_flush()` to trigger the write callback to fire, but this just doesn't work for some reason.)
+
+Once you've created the stream, you need to connect it which involves the whole waiting procedure. This is the same process as the context,
+only this time you'll poll for the state with `pa_stream_get_status()`. The starting and stopping of a streaming is referred to as
+"corking" in PulseAudio. The analogy is corking a barrel. To start the stream, you uncork it, to stop it you cork it. Personally I think
+it's silly - why would you not just call it "starting" and "stopping" like any other normal audio API? Anyway, the act of corking is, you
+guessed it, asynchronous. This means you'll need our waiting loop as usual. Again, why this asynchronous design is the default is
+absolutely beyond me. Would it really be that hard to just make it run synchronously?
+
+Teardown is pretty simple (what?!). It's just a matter of calling the relevant `_unref()` function on each object in reverse order that
+they were initialized in.
+
+That's about it from the PulseAudio side. A bit ranty, I know, but they really need to fix that main loop and callback system. They're
+embarrassingly unpractical. The main loop thing is an easy fix - have synchronous versions of all APIs. If an application wants these to
+run asynchronously, they can execute them in a separate thread themselves. The desire to run these asynchronously is such a niche
+requirement - it makes no sense to make it the default. The stream write callback needs to be change, or an alternative provided, that is
+constantly fired, regardless of whether or not `pa_stream_write()` has been called, and it needs to take a pointer to a buffer as a
+parameter which the program just writes to directly rather than having to call `pa_stream_writable_size()` and `pa_stream_write()`. These
+changes alone will change PulseAudio from one of the worst audio APIs to one of the best.

+Core Audio
+
+So far, Core Audio has been the worst backend to work with due to being both unintuitive and having almost no documentation
+apart from comments in the headers (which admittedly are quite good). For my own purposes, and for anybody out there whose
+needing to figure out how this darn thing works, I'm going to outline a few things here.
+
+Since miniaudio is a fairly low-level API, one of the things it needs is control over specific devices, and it needs to be
+able to identify whether or not it can be used as playback and/or capture. The AudioObject API is the only one I've seen
+that supports this level of detail. There was some public domain sample code I stumbled across that used the AudioComponent
+and AudioUnit APIs, but I couldn't see anything that gave low-level control over device selection and capabilities (the
+distinction between playback and capture in particular). Therefore, miniaudio is using the AudioObject API.
+
+Most (all?) functions in the AudioObject API take a AudioObjectID as it's input. This is the device identifier. When
+retrieving global information, such as the device list, you use kAudioObjectSystemObject. When retrieving device-specific
+data, you pass in the ID for that device. In order to retrieve device-specific IDs you need to enumerate over each of the
+devices. This is done using the AudioObjectGetPropertyDataSize() and AudioObjectGetPropertyData() APIs which seem to be
+the central APIs for retrieving information about the system and specific devices.
+
+To use the AudioObjectGetPropertyData() API you need to use the notion of a property address. A property address is a
+structure with three variables and is used to identify which property you are getting or setting. The first is the "selector"
+which is basically the specific property that you're wanting to retrieve or set. The second is the "scope", which is
+typically set to kAudioObjectPropertyScopeGlobal, kAudioObjectPropertyScopeInput for input-specific properties and
+kAudioObjectPropertyScopeOutput for output-specific properties. The last is the "element" which is always set to
+kAudioObjectPropertyElementMain in miniaudio's case. I don't know of any cases where this would be set to anything different.
+
+Back to the earlier issue of device retrieval, you first use the AudioObjectGetPropertyDataSize() API to retrieve the size
+of the raw data which is just a list of AudioDeviceID's. You use the kAudioObjectSystemObject AudioObjectID, and a property
+address with the kAudioHardwarePropertyDevices selector and the kAudioObjectPropertyScopeGlobal scope. Once you have the
+size, allocate a block of memory of that size and then call AudioObjectGetPropertyData(). The data is just a list of
+AudioDeviceID's so just do "dataSize/sizeof(AudioDeviceID)" to know the device count.

+            https://developer.apple.com/library/archive/technotes/tn2091/_index.html
+
+        This documentation says the following:
+
+            The internal AudioConverter can handle any *simple* conversion. Typically, this means that a client can specify ANY
+            variant of the PCM formats. Consequently, the device's sample rate should match the desired sample rate. If sample rate
+            conversion is needed, it can be accomplished by buffering the input and converting the data on a separate thread with
+            another AudioConverter.
+
+        The important part here is the mention that it can handle *simple* conversions, which does *not* include sample rate. We
+        therefore want to ensure the sample rate stays consistent. This document is specifically for input, but I'm going to play it
+        safe and apply the same rule to output as well.
+
+        I have tried going against the documentation by setting the sample rate anyway, but this just results in AudioUnitRender()
+        returning a result code of -10863. I have also tried changing the format directly on the input scope on the input bus, but
+        this just results in `ca_require: IsStreamFormatWritable(inScope, inElement) NotWritable` when trying to set the format.
+
+        Something that does seem to work, however, has been setting the nominal sample rate on the deivce object. The problem with
+        this, however, is that it actually changes the sample rate at the operating system level and not just the application. This
+        could be intrusive to the user, however, so I don't think it's wise to make this the default. Instead I'm making this a
+        configuration option. When the `coreaudio.allowNominalSampleRateChange` config option is set to true, changing the sample
+        rate will be allowed. Otherwise it'll be fixed to the current sample rate. To check the system-defined sample rate, run
+        the Audio MIDI Setup program that comes installed on macOS and observe how the sample rate changes as the sample rate is
+        changed by miniaudio.

+Note on Starting and Stopping
+=============================
+In the past I was using SNDCTL_DSP_HALT to stop the device, however this results in issues when
+trying to resume the device again. If we use SNDCTL_DSP_HALT, the next write() or read() will
+fail. Instead what we need to do is just not write or read to and from the device when the
+device is not running.
+
+As a result, both the start and stop functions for OSS are just empty stubs. The starting and
+stopping logic is handled by ma_device_write__oss() and ma_device_read__oss(). These will check
+the device state, and if the device is stopped they will simply not do any kind of processing.
+
+The downside to this technique is that I've noticed a fairly lengthy delay in stopping the
+device, up to a second. This is on a virtual machine, and as such might just be due to the
+virtual drivers, but I'm not fully sure. I am not sure how to work around this problem so for
+the moment that's just how it's going to have to be.
+
+When starting the device, OSS will automatically start it when write() or read() is called.

+    If the device is doing playback (ma_device_type_playback or ma_device_type_duplex), there's

+
+    The first is a duplex device for backends that use a callback for data delivery. The reason

+    waits for the playback stage, after which the miniaudio data callback will get fired. This is
+    not needed for backends that use a blocking API because miniaudio manages temporary buffers on
+    the stack to achieve this.
+
+    The other situation is when the data converter does not have the ability to query the number
+    of input frames that are required in order to process a given number of output frames. When
+    performing data conversion, it's useful if miniaudio know exactly how many frames it needs
+    from the client in order to generate a given number of output frames. This way, only exactly
+    the number of frames are needed to be read from the client which means no cache is necessary.
+    On the other hand, if miniaudio doesn't know how many frames to read, it is forced to read
+    in fixed sized chunks and then cache any residual unused input frames, those of which will be
+    processed at a later stage.

+                it's on the opposite side. It will be in the range of -1..1. There's two ways I can think of to
+                calculate a panning value. The first is to simply convert it to 0..1, however this has a problem
+                which I'm not entirely happy with. Considering a stereo system, when a sound is positioned right
+                in front of the listener it'll result in each speaker getting a gain of 0.5. I don't know if I like
+                the idea of having a scaling factor of 0.5 being applied to a sound when it's sitting right in front
+                of the listener. I would intuitively expect that to be played at full volume, or close to it.
+
+                The second idea I think of is to only apply a reduction in gain when the sound is on the opposite
+                side of the speaker. That is, reduce the gain only when the dot product is negative. The problem
+                with this is that there will not be any attenuation as the sound sweeps around the 180 degrees
+                where the dot product is positive. The idea with this option is that you leave the gain at 1 when
+                the sound is being played on the same side as the speaker and then you just reduce the volume when
+                the sound is on the other side.
+
+                The summarize, I think the first option should give a better sense of spatialization, but the second
+                option is better for preserving the sound's power.
+
+                UPDATE: In my testing, I find the first option to sound better. You can feel the sense of space a
+                bit better, but you can also hear the reduction in volume when it's right in front.

+    Imagine the following simplified example: You have a single input speaker which is the front/left speaker which you want to convert to
+    the following output configuration:
+
+     - front/left
+     - side/left
+     - back/left
+
+    The front/left output is easy - it the same speaker position so it receives the full contribution of the front/left input. The amount
+    of contribution to apply to the side/left and back/left speakers, however, is a bit more complicated.
+
+    Imagine the front/left speaker as emitting audio from two planes - the front plane and the left plane. You can think of the front/left
+    speaker emitting half of it's total volume from the front, and the other half from the left. Since part of it's volume is being emitted
+    from the left side, and the side/left and back/left channels also emit audio from the left plane, one would expect that they would
+    receive some amount of contribution from front/left speaker. The amount of contribution depends on how many planes are shared between
+    the two speakers. Note that in the examples below I've added a top/front/left speaker as an example just to show how the math works
+    across 3 spatial dimensions.
+
+    The first thing to do is figure out how each speaker's volume is spread over each of plane:
+     - front/left:     2 planes (front and left)      = 1/2 = half it's total volume on each plane
+     - side/left:      1 plane (left only)            = 1/1 = entire volume from left plane
+     - back/left:      2 planes (back and left)       = 1/2 = half it's total volume on each plane
+     - top/front/left: 3 planes (top, front and left) = 1/3 = one third it's total volume on each plane
+
+    The amount of volume each channel contributes to each of it's planes is what controls how much it is willing to given and take to other
+    channels on the same plane. The volume that is willing to the given by one channel is multiplied by the volume that is willing to be
+    taken by the other to produce the final contribution.

+Log levels are only used to give logging callbacks some context as to the severity of a log message
+so they can do filtering. All log levels will be posted to registered logging callbacks. If you
+don't want to output a certain log level you can discriminate against the log level in the callback.
+
+MA_LOG_LEVEL_DEBUG
+    Used for debugging. Useful for debug and test builds, but should be disabled in release builds.
+
+MA_LOG_LEVEL_INFO
+    Informational logging. Useful for debugging. This will never be called from within the data
+    callback.
+
+MA_LOG_LEVEL_WARNING
+    Warnings. You should enable this in you development builds and action them when encounted. These
+    logs usually indicate a potential problem or misconfiguration, but still allow you to keep
+    running. This will never be called from within the data callback.
+
+MA_LOG_LEVEL_ERROR
+    Error logging. This will be fired when an operation fails and is subsequently aborted. This can
+    be fired from within the data callback, in which case the device will be stopped. You should
+    always have this log level enabled.

+Variables needing to be accessed atomically should be declared with this macro for two reasons:

+Atomics.
+
+These are typesafe structures to prevent errors as a result of forgetting to reference variables atomically. It's too
+easy to introduce subtle bugs where you accidentally do a regular assignment instead of an atomic load/store, etc. By
+using a struct we can enforce the use of atomics at compile time.
+
+These types are declared in the header section because we need to reference them in structs below, but functions for
+using them are only exposed in the implementation section. I do not want these to be part of the public API.
+
+There's a few downsides to this system. The first is that you need to declare a new struct for each type. Below are
+some macros to help with the declarations. They will be named like so:
+
+    ma_atomic_uint32 - atomic ma_uint32
+    ma_atomic_int32  - atomic ma_int32
+    ma_atomic_uint64 - atomic ma_uint64
+    ma_atomic_float  - atomic float
+    ma_atomic_bool32 - atomic ma_bool32
+
+The other downside is that atomic pointers are extremely messy. You need to declare a new struct for each specific
+type of pointer you need to make atomic. For example, an atomic ma_node* will look like this:
+
+    MA_ATOMIC_SAFE_TYPE_IMPL_PTR(node)
+
+Which will declare a type struct that's named like so:
+
+    ma_atomic_ptr_node
+
+Functions to use the atomic types are declared in the implementation section. All atomic functions are prefixed with
+the name of the struct. For example:
+
+    ma_atomic_uint32_set() - Atomic store of ma_uint32
+    ma_atomic_uint32_get() - Atomic load of ma_uint32
+    etc.
+
+For pointer types it's the same, which makes them a bit messy to use due to the length of each function name, but in
+return you get type safety and enforcement of atomic operations.

+The notification callback for when the application should be notified of a change to the device.
+
+This callback is used for notifying the application of changes such as when the device has started,
+stopped, rerouted or an interruption has occurred. Note that not all backends will post all
+notification types. For example, some backends will perform automatic stream routing without any
+kind of notification to the host program which means miniaudio will never know about it and will
+never be able to fire the rerouted notification. You should keep this in mind when designing your
+program.
+
+The stopped notification will *not* get fired when a device is rerouted.
+
+
+Parameters
+----------
+pNotification (in)
+    A pointer to a structure containing information about the event. Use the `pDevice` member of
+    this object to retrieve the relevant device. The `type` member can be used to discriminate
+    against each of the notification types.
+
+
+Remarks
+-------
+Do not restart or uninitialize the device from the callback.
+
+Not all notifications will be triggered by all backends, however the started and stopped events
+should be reliable for all backends. Some backends do not have a good way to detect device
+stoppages due to unplugging the device which may result in the stopped callback not getting
+fired. This has been observed with at least one BSD variant.
+
+The rerouted notification is fired *after* the reroute has occurred. The stopped notification will
+*not* get fired when a device is rerouted. The following backends are known to do automatic stream
+rerouting, but do not have a way to be notified of the change:
+
+  * DirectSound
+
+The interruption notifications are used on mobile platforms for detecting when audio is interrupted
+due to things like an incoming phone call. Currently this is only implemented on iOS. None of the
+Android backends will report this notification.

+The callback for processing audio data from the device.
+
+The data callback is fired by miniaudio whenever the device needs to have more data delivered to a playback device, or when a capture device has some data
+available. This is called as soon as the backend asks for more data which means it may be called with inconsistent frame counts. You cannot assume the
+callback will be fired with a consistent frame count.
+
+
+Parameters
+----------
+pDevice (in)
+    A pointer to the relevant device.
+
+pOutput (out)
+    A pointer to the output buffer that will receive audio data that will later be played back through the speakers. This will be non-null for a playback or
+    full-duplex device and null for a capture and loopback device.
+
+pInput (in)
+    A pointer to the buffer containing input data from a recording device. This will be non-null for a capture, full-duplex or loopback device and null for a
+    playback device.
+
+frameCount (in)
+    The number of PCM frames to process. Note that this will not necessarily be equal to what you requested when you initialized the device. The
+    `periodSizeInFrames` and `periodSizeInMilliseconds` members of the device config are just hints, and are not necessarily exactly what you'll get. You must
+    not assume this will always be the same value each time the callback is fired.
+
+
+Remarks
+-------
+You cannot stop and start the device from inside the callback or else you'll get a deadlock. You must also not uninitialize the device from inside the
+callback. The following APIs cannot be called from inside the callback:
+
+    ma_device_init()
+    ma_device_init_ex()
+    ma_device_uninit()
+    ma_device_start()
+    ma_device_stop()
+
+The proper way to stop the device is to call `ma_device_stop()` from a different thread, normally the main application thread.

+/*
+These are the callbacks required to be implemented for a backend. These callbacks are grouped into two parts: context and device. There is one context
+to many devices. A device is created from a context.
+
+The general flow goes like this:
+
+  1) A context is created with `onContextInit()`
+     1a) Available devices can be enumerated with `onContextEnumerateDevices()` if required.
+     1b) Detailed information about a device can be queried with `onContextGetDeviceInfo()` if required.
+  2) A device is created from the context that was created in the first step using `onDeviceInit()`, and optionally a device ID that was
+     selected from device enumeration via `onContextEnumerateDevices()`.
+  3) A device is started or stopped with `onDeviceStart()` / `onDeviceStop()`
+  4) Data is delivered to and from the device by the backend. This is always done based on the native format returned by the prior call
+     to `onDeviceInit()`. Conversion between the device's native format and the format requested by the application will be handled by
+     miniaudio internally.
+
+Initialization of the context is quite simple. You need to do any necessary initialization of internal objects and then output the
+callbacks defined in this structure.
+
+Once the context has been initialized you can initialize a device. Before doing so, however, the application may want to know which
+physical devices are available. This is where `onContextEnumerateDevices()` comes in. This is fairly simple. For each device, fire the
+given callback with, at a minimum, the basic information filled out in `ma_device_info`. When the callback returns `MA_FALSE`, enumeration
+needs to stop and the `onContextEnumerateDevices()` function returns with a success code.
+
+Detailed device information can be retrieved from a device ID using `onContextGetDeviceInfo()`. This takes as input the device type and ID,
+and on output returns detailed information about the device in `ma_device_info`. The `onContextGetDeviceInfo()` callback must handle the
+case when the device ID is NULL, in which case information about the default device needs to be retrieved.
+
+Once the context has been created and the device ID retrieved (if using anything other than the default device), the device can be created.
+This is a little bit more complicated than initialization of the context due to it's more complicated configuration. When initializing a
+device, a duplex device may be requested. This means a separate data format needs to be specified for both playback and capture. On input,
+the data format is set to what the application wants. On output it's set to the native format which should match as closely as possible to
+the requested format. The conversion between the format requested by the application and the device's native format will be handled
+internally by miniaudio.
+
+On input, if the sample format is set to `ma_format_unknown`, the backend is free to use whatever sample format it desires, so long as it's
+supported by miniaudio. When the channel count is set to 0, the backend should use the device's native channel count. The same applies for
+sample rate. For the channel map, the default should be used when `ma_channel_map_is_blank()` returns true (all channels set to
+`MA_CHANNEL_NONE`). On input, the `periodSizeInFrames` or `periodSizeInMilliseconds` option should always be set. The backend should
+inspect both of these variables. If `periodSizeInFrames` is set, it should take priority, otherwise it needs to be derived from the period
+size in milliseconds (`periodSizeInMilliseconds`) and the sample rate, keeping in mind that the sample rate may be 0, in which case the
+sample rate will need to be determined before calculating the period size in frames. On output, all members of the `ma_device_descriptor`
+object should be set to a valid value, except for `periodSizeInMilliseconds` which is optional (`periodSizeInFrames` *must* be set).
+
+Starting and stopping of the device is done with `onDeviceStart()` and `onDeviceStop()` and should be self-explanatory. If the backend uses
+asynchronous reading and writing, `onDeviceStart()` and `onDeviceStop()` should always be implemented.
+
+The handling of data delivery between the application and the device is the most complicated part of the process. To make this a bit
+easier, some helper callbacks are available. If the backend uses a blocking read/write style of API, the `onDeviceRead()` and
+`onDeviceWrite()` callbacks can optionally be implemented. These are blocking and work just like reading and writing from a file. If the
+backend uses a callback for data delivery, that callback must call `ma_device_handle_backend_data_callback()` from within it's callback.
+This allows miniaudio to then process any necessary data conversion and then pass it to the miniaudio data callback.
+
+If the backend requires absolute flexibility with it's data delivery, it can optionally implement the `onDeviceDataLoop()` callback
+which will allow it to implement the logic that will run on the audio thread. This is much more advanced and is completely optional.
+
+The audio thread should run data delivery logic in a loop while `ma_device_get_state() == ma_device_state_started` and no errors have been
+encountered. Do not start or stop the device here. That will be handled from outside the `onDeviceDataLoop()` callback.
+
+The invocation of the `onDeviceDataLoop()` callback will be handled by miniaudio. When you start the device, miniaudio will fire this
+callback. When the device is stopped, the `ma_device_get_state() == ma_device_state_started` condition will fail and the loop will be terminated
+which will then fall through to the part that stops the device. For an example on how to implement the `onDeviceDataLoop()` callback,
+look at `ma_device_audio_thread__default_read_write()`. Implement the `onDeviceDataLoopWakeup()` callback if you need a mechanism to
+wake up the audio thread.
+
+If the backend supports an optimized retrieval of device information from an initialized `ma_device` object, it should implement the
+`onDeviceGetInfo()` callback. This is optional, in which case it will fall back to `onContextGetDeviceInfo()` which is less efficient.

+Initializes a context.
+
+The context is used for selecting and initializing an appropriate backend and to represent the backend at a more global level than that of an individual
+device. There is one context to many devices, and a device is created from a context. A context is required to enumerate devices.
+
+
+Parameters
+----------
+backends (in, optional)
+    A list of backends to try initializing, in priority order. Can be NULL, in which case it uses default priority order.
+
+backendCount (in, optional)
+    The number of items in `backend`. Ignored if `backend` is NULL.
+
+pConfig (in, optional)
+    The context configuration.
+
+pContext (in)
+    A pointer to the context object being initialized.
+
+
+Return Value
+------------
+MA_SUCCESS if successful; any other error code otherwise.
+
+
+Thread Safety
+-------------
+Unsafe. Do not call this function across multiple threads as some backends read and write to global state.

+        A pointer to the `ma_log` to post log messages to. Can be NULL if the application does not

+
+    threadPriority
+        The desired priority to use for the audio thread. Allowable values include the following:
+
+        |--------------------------------------|
+        | Thread Priority                      |

+        | ma_thread_priority_default           |
+        |--------------------------------------|
+
+    threadStackSize
+        The desired size of the stack for the audio thread. Defaults to the operating system's default.
+
+    pUserData
+        A pointer to application-defined data. This can be accessed from the context object directly such as `context.pUserData`.
+
+    allocationCallbacks
+        Structure containing custom allocation callbacks. Leaving this at defaults will cause it to use MA_MALLOC, MA_REALLOC and MA_FREE. These allocation
+        callbacks will be used for anything tied to the context, including devices.
+
+    alsa.useVerboseDeviceEnumeration
+        ALSA will typically enumerate many different devices which can be intrusive and not user-friendly. To combat this, miniaudio will enumerate only unique
+        card/device pairs by default. The problem with this is that you lose a bit of flexibility and control. Setting alsa.useVerboseDeviceEnumeration makes
+        it so the ALSA backend includes all devices. Defaults to false.
+
+    pulse.pApplicationName
+        PulseAudio only. The application name to use when initializing the PulseAudio context with `pa_context_new()`.
+
+    pulse.pServerName
+        PulseAudio only. The name of the server to connect to with `pa_context_connect()`.
+
+    pulse.tryAutoSpawn
+        PulseAudio only. Whether or not to try automatically starting the PulseAudio daemon. Defaults to false. If you set this to true, keep in mind that
+        miniaudio uses a trial and error method to find the most appropriate backend, and this will result in the PulseAudio daemon starting which may be
+        intrusive for the end user.
+
+    coreaudio.sessionCategory
+        iOS only. The session category to use for the shared AudioSession instance. Below is a list of allowable values and their Core Audio equivalents.

+        iOS only. When set to true, does not perform an explicit [[AVAudioSession sharedInstace] setActive:false] on uninitialization.
+
+    jack.pClientName
+        The name of the client to pass to `jack_client_open()`.
+
+    jack.tryStartServer
+        Whether or not to try auto-starting the JACK server. Defaults to false.
+
+
+It is recommended that only a single context is active at any given time because it's a bulky data structure which performs run-time linking for the
+relevant backends every time it's initialized.
+
+The location of the context cannot change throughout it's lifetime. Consider allocating the `ma_context` object with `malloc()` if this is an issue. The
+reason for this is that a pointer to the context is stored in the `ma_device` structure.
+
+
+Example 1 - Default Initialization
+----------------------------------
+The example below shows how to initialize the context using the default configuration.
+
+```c
+ma_context context;
+ma_result result = ma_context_init(NULL, 0, NULL, &context);
+if (result != MA_SUCCESS) {
+    // Error.
+}
+```
+
+
+Example 2 - Custom Configuration
+--------------------------------
+The example below shows how to initialize the context using custom backend priorities and a custom configuration. In this hypothetical example, the program
+wants to prioritize ALSA over PulseAudio on Linux. They also want to avoid using the WinMM backend on Windows because it's latency is too high. They also
+want an error to be returned if no valid backend is available which they achieve by excluding the Null backend.
+
+For the configuration, the program wants to capture any log messages so they can, for example, route it to a log file and user interface.
+
+```c

+The example below is what a program will typically want to configure for each device at a minimum. Notice how `ma_device_config_init()` is called first, and

+MA_API ma_device_config ma_device_config_init(ma_device_type deviceType);

+
+/*
+Initializes a device.
+
+A device represents a physical audio device. The idea is you send or receive audio data from the device to either play it back through a speaker, or capture it
+from a microphone. Whether or not you should send or receive data from the device (or both) depends on the type of device you are initializing which can be
+playback, capture, full-duplex or loopback. (Note that loopback mode is only supported on select backends.) Sending and receiving audio data to and from the
+device is done via a callback which is fired by miniaudio at periodic time intervals.
+
+The frequency at which data is delivered to and from a device depends on the size of it's period. The size of the period can be defined in terms of PCM frames
+or milliseconds, whichever is more convenient. Generally speaking, the smaller the period, the lower the latency at the expense of higher CPU usage and
+increased risk of glitching due to the more frequent and granular data deliver intervals. The size of a period will depend on your requirements, but
+miniaudio's defaults should work fine for most scenarios. If you're building a game you should leave this fairly small, whereas if you're building a simple
+media player you can make it larger. Note that the period size you request is actually just a hint - miniaudio will tell the backend what you want, but the
+backend is ultimately responsible for what it gives you. You cannot assume you will get exactly what you ask for.
+
+When delivering data to and from a device you need to make sure it's in the correct format which you can set through the device configuration. You just set the
+format that you want to use and miniaudio will perform all of the necessary conversion for you internally. When delivering data to and from the callback you
+can assume the format is the same as what you requested when you initialized the device. See Remarks for more details on miniaudio's data conversion pipeline.
+
+
+Parameters
+----------
+pContext (in, optional)
+    A pointer to the context that owns the device. This can be null, in which case it creates a default context internally.
+
+pConfig (in)
+    A pointer to the device configuration. Cannot be null. See remarks for details.
+
+pDevice (out)
+    A pointer to the device object being initialized.
+
+
+Return Value
+------------
+MA_SUCCESS if successful; any other error code otherwise.
+
+
+Thread Safety
+-------------
+Unsafe. It is not safe to call this function simultaneously for different devices because some backends depend on and mutate global state. The same applies to
+calling this at the same time as `ma_device_uninit()`.
+
+
+Callback Safety
+---------------
+Unsafe. It is not safe to call this inside any callback.
+
+
+Remarks
+-------
+Setting `pContext` to NULL will result in miniaudio creating a default context internally and is equivalent to passing in a context initialized like so:
+
+    ```c
+    ma_context_init(NULL, 0, NULL, &context);
+    ```
+
+Do not set `pContext` to NULL if you are needing to open multiple devices. You can, however, use NULL when initializing the first device, and then use
+device.pContext for the initialization of other devices.
+
+The device can be configured via the `pConfig` argument. The config object is initialized with `ma_device_config_init()`. Individual configuration settings can
+then be set directly on the structure. Below are the members of the `ma_device_config` object.
+
+    deviceType
+        Must be `ma_device_type_playback`, `ma_device_type_capture`, `ma_device_type_duplex` of `ma_device_type_loopback`.
+
+    sampleRate
+        The sample rate, in hertz. The most common sample rates are 48000 and 44100. Setting this to 0 will use the device's native sample rate.
+
+    periodSizeInFrames
+        The desired size of a period in PCM frames. If this is 0, `periodSizeInMilliseconds` will be used instead. If both are 0 the default buffer size will
+        be used depending on the selected performance profile. This value affects latency. See below for details.
+
+    periodSizeInMilliseconds
+        The desired size of a period in milliseconds. If this is 0, `periodSizeInFrames` will be used instead. If both are 0 the default buffer size will be
+        used depending on the selected performance profile. The value affects latency. See below for details.
+
+    periods
+        The number of periods making up the device's entire buffer. The total buffer size is `periodSizeInFrames` or `periodSizeInMilliseconds` multiplied by
+        this value. This is just a hint as backends will be the ones who ultimately decide how your periods will be configured.
+
+    performanceProfile
+        A hint to miniaudio as to the performance requirements of your program. Can be either `ma_performance_profile_low_latency` (default) or
+        `ma_performance_profile_conservative`. This mainly affects the size of default buffers and can usually be left at it's default value.
+
+    noPreSilencedOutputBuffer
+        When set to true, the contents of the output buffer passed into the data callback will be left undefined. When set to false (default), the contents of
+        the output buffer will be cleared the zero. You can use this to avoid the overhead of zeroing out the buffer if you can guarantee that your data
+        callback will write to every sample in the output buffer, or if you are doing your own clearing.
+
+    noClip
+        When set to true, the contents of the output buffer are left alone after returning and it will be left up to the backend itself to decide whether or
+        not to clip. When set to false (default), the contents of the output buffer passed into the data callback will be clipped after returning. This only
+        applies when the playback sample format is f32.
+
+    noDisableDenormals
+        By default, miniaudio will disable denormals when the data callback is called. Setting this to true will prevent the disabling of denormals.
+
+    noFixedSizedCallback
+        Allows miniaudio to fire the data callback with any frame count. When this is set to false (the default), the data callback will be fired with a
+        consistent frame count as specified by `periodSizeInFrames` or `periodSizeInMilliseconds`. When set to true, miniaudio will fire the callback with
+        whatever the backend requests, which could be anything.
+
+    dataCallback
+        The callback to fire whenever data is ready to be delivered to or from the device.
+
+    notificationCallback
+        The callback to fire when something has changed with the device, such as whether or not it has been started or stopped.
+
+    pUserData
+        The user data pointer to use with the device. You can access this directly from the device object like `device.pUserData`.
+
+    resampling.algorithm
+        The resampling algorithm to use when miniaudio needs to perform resampling between the rate specified by `sampleRate` and the device's native rate. The
+        default value is `ma_resample_algorithm_linear`, and the quality can be configured with `resampling.linear.lpfOrder`.
+
+    resampling.pBackendVTable
+        A pointer to an optional vtable that can be used for plugging in a custom resampler.
+
+    resampling.pBackendUserData
+        A pointer that will passed to callbacks in pBackendVTable.
+
+    resampling.linear.lpfOrder
+        The linear resampler applies a low-pass filter as part of it's processing for anti-aliasing. This setting controls the order of the filter. The higher
+        the value, the better the quality, in general. Setting this to 0 will disable low-pass filtering altogether. The maximum value is
+        `MA_MAX_FILTER_ORDER`. The default value is `min(4, MA_MAX_FILTER_ORDER)`.
+
+    playback.pDeviceID
+        A pointer to a `ma_device_id` structure containing the ID of the playback device to initialize. Setting this NULL (default) will use the system's
+        default playback device. Retrieve the device ID from the `ma_device_info` structure, which can be retrieved using device enumeration.
+
+    playback.format
+        The sample format to use for playback. When set to `ma_format_unknown` the device's native format will be used. This can be retrieved after
+        initialization from the device object directly with `device.playback.format`.
+
+    playback.channels
+        The number of channels to use for playback. When set to 0 the device's native channel count will be used. This can be retrieved after initialization
+        from the device object directly with `device.playback.channels`.
+
+    playback.pChannelMap
+        The channel map to use for playback. When left empty, the device's native channel map will be used. This can be retrieved after initialization from the
+        device object direct with `device.playback.pChannelMap`. When set, the buffer should contain `channels` items.
+
+    playback.shareMode
+        The preferred share mode to use for playback. Can be either `ma_share_mode_shared` (default) or `ma_share_mode_exclusive`. Note that if you specify
+        exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired by changing this to
+        ma_share_mode_shared and reinitializing.
+
+    capture.pDeviceID
+        A pointer to a `ma_device_id` structure containing the ID of the capture device to initialize. Setting this NULL (default) will use the system's
+        default capture device. Retrieve the device ID from the `ma_device_info` structure, which can be retrieved using device enumeration.
+
+    capture.format
+        The sample format to use for capture. When set to `ma_format_unknown` the device's native format will be used. This can be retrieved after
+        initialization from the device object directly with `device.capture.format`.
+
+    capture.channels
+        The number of channels to use for capture. When set to 0 the device's native channel count will be used. This can be retrieved after initialization
+        from the device object directly with `device.capture.channels`.
+
+    capture.pChannelMap
+        The channel map to use for capture. When left empty, the device's native channel map will be used. This can be retrieved after initialization from the
+        device object direct with `device.capture.pChannelMap`. When set, the buffer should contain `channels` items.
+
+    capture.shareMode
+        The preferred share mode to use for capture. Can be either `ma_share_mode_shared` (default) or `ma_share_mode_exclusive`. Note that if you specify
+        exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired by changing this to
+        ma_share_mode_shared and reinitializing.
+
+    wasapi.noAutoConvertSRC
+        WASAPI only. When set to true, disables WASAPI's automatic resampling and forces the use of miniaudio's resampler. Defaults to false.
+
+    wasapi.noDefaultQualitySRC
+        WASAPI only. Only used when `wasapi.noAutoConvertSRC` is set to false. When set to true, disables the use of `AUDCLNT_STREAMFLAGS_SRC_DEFAULT_QUALITY`.
+        You should usually leave this set to false, which is the default.
+
+    wasapi.noAutoStreamRouting
+        WASAPI only. When set to true, disables automatic stream routing on the WASAPI backend. Defaults to false.
+
+    wasapi.noHardwareOffloading
+        WASAPI only. When set to true, disables the use of WASAPI's hardware offloading feature. Defaults to false.
+
+    alsa.noMMap
+        ALSA only. When set to true, disables MMap mode. Defaults to false.
+
+    alsa.noAutoFormat
+        ALSA only. When set to true, disables ALSA's automatic format conversion by including the SND_PCM_NO_AUTO_FORMAT flag. Defaults to false.
+
+    alsa.noAutoChannels
+        ALSA only. When set to true, disables ALSA's automatic channel conversion by including the SND_PCM_NO_AUTO_CHANNELS flag. Defaults to false.
+
+    alsa.noAutoResample
+        ALSA only. When set to true, disables ALSA's automatic resampling by including the SND_PCM_NO_AUTO_RESAMPLE flag. Defaults to false.
+
+    pulse.pStreamNamePlayback
+        PulseAudio only. Sets the stream name for playback.
+
+    pulse.pStreamNameCapture
+        PulseAudio only. Sets the stream name for capture.
+
+    coreaudio.allowNominalSampleRateChange
+        Core Audio only. Desktop only. When enabled, allows the sample rate of the device to be changed at the operating system level. This
+        is disabled by default in order to prevent intrusive changes to the user's system. This is useful if you want to use a sample rate
+        that is known to be natively supported by the hardware thereby avoiding the cost of resampling. When set to true, miniaudio will
+        find the closest match between the sample rate requested in the device config and the sample rates natively supported by the
+        hardware. When set to false, the sample rate currently set by the operating system will always be used.
+
+    opensl.streamType
+        OpenSL only. Explicitly sets the stream type. If left unset (`ma_opensl_stream_type_default`), the
+        stream type will be left unset. Think of this as the type of audio you're playing.
+
+    opensl.recordingPreset
+        OpenSL only. Explicitly sets the type of recording your program will be doing. When left
+        unset, the recording preset will be left unchanged.
+
+    aaudio.usage
+        AAudio only. Explicitly sets the nature of the audio the program will be consuming. When
+        left unset, the usage will be left unchanged.
+
+    aaudio.contentType
+        AAudio only. Sets the content type. When left unset, the content type will be left unchanged.
+
+    aaudio.inputPreset
+        AAudio only. Explicitly sets the type of recording your program will be doing. When left
+        unset, the input preset will be left unchanged.
+
+    aaudio.noAutoStartAfterReroute
+        AAudio only. Controls whether or not the device should be automatically restarted after a
+        stream reroute. When set to false (default) the device will be restarted automatically;
+        otherwise the device will be stopped.
+
+
+Once initialized, the device's config is immutable. If you need to change the config you will need to initialize a new device.
+
+After initializing the device it will be in a stopped state. To start it, use `ma_device_start()`.
+
+If both `periodSizeInFrames` and `periodSizeInMilliseconds` are set to zero, it will default to `MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_LOW_LATENCY` or
+`MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_CONSERVATIVE`, depending on whether or not `performanceProfile` is set to `ma_performance_profile_low_latency` or
+`ma_performance_profile_conservative`.
+
+If you request exclusive mode and the backend does not support it an error will be returned. For robustness, you may want to first try initializing the device
+in exclusive mode, and then fall back to shared mode if required. Alternatively you can just request shared mode (the default if you leave it unset in the
+config) which is the most reliable option. Some backends do not have a practical way of choosing whether or not the device should be exclusive or not (ALSA,
+for example) in which case it just acts as a hint. Unless you have special requirements you should try avoiding exclusive mode as it's intrusive to the user.
+Starting with Windows 10, miniaudio will use low-latency shared mode where possible which may make exclusive mode unnecessary.
+
+When sending or receiving data to/from a device, miniaudio will internally perform a format conversion to convert between the format specified by the config
+and the format used internally by the backend. If you pass in 0 for the sample format, channel count, sample rate _and_ channel map, data transmission will run
+on an optimized pass-through fast path. You can retrieve the format, channel count and sample rate by inspecting the `playback/capture.format`,
+`playback/capture.channels` and `sampleRate` members of the device object.
+
+When compiling for UWP you must ensure you call this function on the main UI thread because the operating system may need to present the user with a message
+asking for permissions. Please refer to the official documentation for ActivateAudioInterfaceAsync() for more information.
+
+ALSA Specific: When initializing the default device, requesting shared mode will try using the "dmix" device for playback and the "dsnoop" device for capture.
+If these fail it will try falling back to the "hw" device.
+
+
+Example 1 - Simple Initialization
+---------------------------------
+This example shows how to initialize a simple playback device using a standard configuration. If you are just needing to do simple playback from the default
+playback device this is usually all you need.
+
+```c
+ma_device_config config = ma_device_config_init(ma_device_type_playback);
+config.playback.format   = ma_format_f32;
+config.playback.channels = 2;
+config.sampleRate        = 48000;
+config.dataCallback      = ma_data_callback;
+config.pMyUserData       = pMyUserData;
+
+ma_device device;
+ma_result result = ma_device_init(NULL, &config, &device);
+if (result != MA_SUCCESS) {
+    // Error
+}
+```
+
+
+Example 2 - Advanced Initialization
+-----------------------------------
+This example shows how you might do some more advanced initialization. In this hypothetical example we want to control the latency by setting the buffer size
+and period count. We also want to allow the user to be able to choose which device to output from which means we need a context so we can perform device
+enumeration.
+
+```c
+ma_context context;
+ma_result result = ma_context_init(NULL, 0, NULL, &context);
+if (result != MA_SUCCESS) {
+    // Error
+}
+
+ma_device_info* pPlaybackDeviceInfos;
+ma_uint32 playbackDeviceCount;
+result = ma_context_get_devices(&context, &pPlaybackDeviceInfos, &playbackDeviceCount, NULL, NULL);
+if (result != MA_SUCCESS) {
+    // Error
+}
+
+// ... choose a device from pPlaybackDeviceInfos ...
+
+ma_device_config config = ma_device_config_init(ma_device_type_playback);
+config.playback.pDeviceID       = pMyChosenDeviceID;    // <-- Get this from the `id` member of one of the `ma_device_info` objects returned by ma_context_get_devices().
+config.playback.format          = ma_format_f32;
+config.playback.channels        = 2;
+config.sampleRate               = 48000;
+config.dataCallback             = ma_data_callback;
+config.pUserData                = pMyUserData;
+config.periodSizeInMilliseconds = 10;
+config.periods                  = 3;
+
+ma_device device;
+result = ma_device_init(&context, &config, &device);
+if (result != MA_SUCCESS) {
+    // Error

+    A pointer to the buffer that will receive the enabled backends. Set to NULL to retrieve the backend count. Setting
+    the capacity of the buffer to `MA_BUFFER_COUNT` will guarantee it's large enough for all backends.
+
+backendCap (in)
+    The capacity of the `pBackends` buffer.
+
+pBackendCount (out)
+    A pointer to the variable that will receive the enabled backend count.
+
+
+Return Value
+------------
+MA_SUCCESS if successful.
+MA_INVALID_ARGS if `pBackendCount` is NULL.
+MA_NO_SPACE if the capacity of `pBackends` is not large enough.
+
+If `MA_NO_SPACE` is returned, the `pBackends` buffer will be filled with `*pBackendCount` values.
+
+
+Thread Safety
+-------------
+Safe.
+
+
+Callback Safety
+---------------
+Safe.
+
+
+Remarks
+-------
+If you want to retrieve the number of backends so you can determine the capacity of `pBackends` buffer, you can call
+this function with `pBackends` set to NULL.
+
+This will also enumerate the null backend. If you don't want to include this you need to check for `ma_backend_null`
+when you enumerate over the returned backends and handle it appropriately. Alternatively, you can disable it at
+compile time with `MA_NO_NULL`.
+
+The returned backends are determined based on compile time settings, not the platform it's currently running on. For
+example, PulseAudio will be returned if it was enabled at compile time, even when the user doesn't actually have
+PulseAudio installed.
+
+
+Example 1
+---------
+The example below retrieves the enabled backend count using a fixed sized buffer allocated on the stack. The buffer is
+given a capacity of `MA_BACKEND_COUNT` which will guarantee it'll be large enough to store all available backends.
+Since `MA_BACKEND_COUNT` is always a relatively small value, this should be suitable for most scenarios.
+
+```
+ma_backend enabledBackends[MA_BACKEND_COUNT];
+size_t enabledBackendCount;
+
+result = ma_get_enabled_backends(enabledBackends, MA_BACKEND_COUNT, &enabledBackendCount);
+if (result != MA_SUCCESS) {
+    // Failed to retrieve enabled backends. Should never happen in this example since all inputs are valid.
+}
+```
