NAME
SDL_GetAudioStreamAvailable - Get the number of converted/resampled bytes available.
HEADER FILE
Defined in SDL3/SDL_audio.h
SYNOPSIS
#include "SDL3/SDL.h"
int SDL_GetAudioStreamAvailable(SDL_AudioStream *stream);
DESCRIPTION
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.
FUNCTION PARAMETERS
stream the audio stream to query.
RETURN VALUE
Returns the number of converted/resampled bytes available or -1 on failure; call SDL_GetError () for more
information.
THREAD SAFETY
It is safe to call this function from any thread.
AVAILABILITY
This function is available since SDL 3.2.0.
