NAME¶

SDL_PutAudioStreamData - Add data to be converted/resampled to the stream.

SYNOPSIS¶

#include "SDL3/SDL.h"

int SDL_PutAudioStreamData(SDL_AudioStream *stream, const void *buf, int len);

DESCRIPTION¶

This data must match the format/channels/samplerate specified in the latest call to SDL_SetAudioStreamFormat , or the format specified when creating the stream if it hasn't been changed.

Note that this call simply queues unconverted data for later. This is different than SDL2, where data was converted during the Put call and the Get call would just dequeue the previously-converted data.

FUNCTION PARAMETERS¶

stream

The stream the audio data is being added to

buf

A pointer to the audio data to add

len

The number of bytes to write to the stream

RETURN VALUE¶

Returns 0 on success or a negative error code on failure; call

SDL_GetError () for more information.

THREAD SAFETY¶

It is safe to call this function from any thread, but if the stream has a callback set, the caller might need to manage extra locking.

AVAILABILITY¶

This function is available since SDL 3.0.0.
