SDL_GetAudioStreamInputChannelMap - Get the current input channel map of an audio stream.

       This function is available since SDL 3.2.0.

       Channel  maps  are  optional;  most  things do not need them, instead passing data in the [order that SDL
       expects](CategoryAudio#channel-layouts).

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

stream the SDL_AudioStream
               to query.

       count  On output, set to number of channels in the map. Can be NULL.
