ogg_sync_wrote

declared in "ogg/ogg.h";

This function is used to tell the ogg_sync_state struct how many bytes we wrote into the buffer.

The general proceedure is to request a pointer into an internal ogg_sync_state buffer by calling ogg_sync_buffer(). The buffer is then filled up to the requested size with new input, and ogg_sync_wrote() is called to advance the fill pointer by however much data was actually available.

int ogg_sync_wrote(ogg_sync_state *oy, long bytes);

Parameters

oy

Pointer to a previously declared ogg_sync_state struct.

bytes

Number of bytes of new data written.

Return Values

-1 if the number of bytes written overflows the internal storage of the ogg_sync_state struct.

0 in all other cases.
