sdlGetAudioStreamInputChannelMap function

Pointer<Int32> sdlGetAudioStreamInputChannelMap(Pointer<SdlAudioStream> stream, Pointer<Int32> count)

Get the current input channel map of an audio stream.

Channel maps are optional; most things do not need them, instead passing data in the order that SDL expects.

Audio streams default to no remapping applied. This is represented by returning NULL, and does not signify an error.

\param stream the SDL_AudioStream to query. \param count On output, set to number of channels in the map. Can be NULL. \returns an array of the current channel mapping, with as many elements as the current output spec's channels, or NULL if default. This should be freed with SDL_free() when it is no longer needed.

\threadsafety It is safe to call this function from any thread, as it holds a stream-specific mutex while running.

\since This function is available since SDL 3.1.3.
