```
In the example above, the memory pointed to by `pExistingData` will _not_ be copied and is how an application can do self-managed memory allocation. If you
would rather make a copy of the data, use `ma_audio_buffer_init_copy()`. To uninitialize the buffer, use `ma_audio_buffer_uninit()`.
Sometimes it can be convenient to allocate the memory for the `ma_audio_buffer` structure _and_ the raw audio data in a contiguous block of memory. That is,
the raw audio data will be located immediately after the `ma_audio_buffer` structure. To do this, use `ma_audio_buffer_alloc_and_init()`:
```c
ma_audio_buffer_config config = ma_audio_buffer_config_init(

channels,

MA_SUCCESS if successful; any other error code otherwise.
Thread Safety
-------------
Safe. This is guarded using a simple mutex lock.
Remarks
-------
Do _not_ assume the first enumerated device of a given type is the default device.
Some backends and platforms may only support default playback and capture devices.
In general, you should not do anything complicated from within the callback. In particular, do not try initializing a device from within the callback. Also,
do not try to call `ma_context_get_device_info()` from within the callback.
Consider using `ma_context_get_devices()` for a simpler and safer API, albeit at the expense of an internal heap allocation.
Example 1 - Simple Enumeration
share/public_html/static/music_inc/src/miniaudio.h view on Meta::CPAN
Thread Safety
-------------
Unsafe. Since each call to this function invalidates the pointers from the previous call, you should not be calling this simultaneously across multiple
threads. Instead, you need to make a copy of the returned data with your own higher level synchronization.
Remarks
-------
It is _not_ safe to assume the first device in the list is the default device.
You can pass in NULL for the playback or capture lists in which case they'll be ignored.
The returned pointers will become invalid upon the next call this this function, or when the context is uninitialized. Do not free the returned pointers.

MA_SUCCESS if successful; any other error code otherwise.
Thread Safety
-------------
Safe. This is guarded using a simple mutex lock.
Remarks
-------
Do _not_ call this from within the `ma_context_enumerate_devices()` callback.
It's possible for a device to have different information and capabilities depending on whether or not it's opened in shared or exclusive mode. For example, in
shared mode, WASAPI always uses floating point samples for mixing, but in exclusive mode it can be anything. Therefore, this function allows you to specify
which share mode you want information for. Note that not all backends and devices support shared or exclusive mode, in which case this function will fail if
the requested share mode is unsupported.
This leaves pDeviceInfo unmodified in the result of an error.

Random Number Generation
miniaudio uses the LCG random number generation algorithm. This is good enough for audio.
Note that miniaudio's global LCG implementation uses global state which is _not_ thread-local. When this is called across

miniaudio's purposes.

Do _not_ call this from within the `ma_context_enumerate_devices()` callback.
It's possible for a device to have different information and capabilities depending on whether or not it's opened in shared or exclusive mode. For example, in
shared mode, WASAPI always uses floating point samples for mixing, but in exclusive mode it can be anything. Therefore, this function allows you to specify
which share mode you want information for. Note that not all backends and devices support shared or exclusive mode, in which case this function will fail if
the requested share mode is unsupported.
This leaves pDeviceInfo unmodified in the result of an error.

Random Number Generation
miniaudio uses the LCG random number generation algorithm. This is good enough for audio.
Note that miniaudio's global LCG implementation uses global state which is _not_ thread-local. When this is called across
multiple threads, results will be unpredictable. However, it won't crash and results will still be random enough for
miniaudio's purposes.
