SDL_GetAudioStreamAvailable - Get the number of converted/resampled bytes available.

       This function is available since SDL 3.2.0.

       The  stream  may  be  buffering data behind the scenes until it has enough to resample correctly, so this
       number might be lower than what you expect, or even be zero. Add more data or flush  the  stream  if  you
       need the data now.

       If  the  stream  has so much data that it would overflow an int, the return value is clamped to a maximum
       value, but no queued data is lost; if there are gigabytes of data queued, the app might need to read some
       of it with SDL_GetAudioStreamData before this function's return value is no longer clamped.

stream the audio stream to query.
