free_audio_stream_buffer(3alleg4) Allegro manual free_audio_stream_buffer(3alleg4)NAME
free_audio_stream_buffer - Tells the audio stream player new data can be played. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
void free_audio_stream_buffer(AUDIOSTREAM *stream);
DESCRIPTION
Call this function after get_audio_stream_buffer() returns a non-NULL address, to indicate that you have loaded a new block of samples to
that location and the data is now ready to be played. Example:
mem_chunk = get_audio_stream_buffer(buffer);
if (mem_chunk != NULL) {
/* Refill the stream buffer. */
...
free_audio_stream_buffer(buffer);
}

get_audio_stream_buffer - Tells you if you need to fill the audiostream or not. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
void *get_audio_stream_buffer(AUDIOSTREAM *stream);
DESCRIPTION
You must call this function at regular intervals while an audio stream is playing, to provide the next buffer of sample data (the smaller
the stream buffer size, the more often it must be called). This function should not be called from a timer handler. Example:
void *mem_chunk;
...
while (TRUE) {
...
mem_chunk = get_audio_stream_buffer(buffer);
if (mem_chunk != NULL) {
/* Refill the stream buffer. */
}
}
RETURN VALUE
If it returns NULL, the stream is still playing the previous lot of data, so you don't need to do anything. If it returns a value, that is
the location of the next buffer to be played, and you should load the appropriate number of samples (however many you specified when creat-
ing the stream) to that address, for example using an fread() from a disk file. After filling the buffer with data, call
free_audio_stream_buffer() to indicate that the new data is now valid.
