20 <p>This function is used to tell the <a href="ogg_sync_state.html">ogg_sync_state</a> struct how many bytes we wrote into the buffer.
|

Chris@1

Chris@1

|
|
Chris@1
|
23 The general proceedure is to request a pointer into an internal
|
|
Chris@1
|
24 <a href="ogg_sync_state.html">ogg_sync_state</a> buffer by calling
|
|
Chris@1
|
25 <a href="ogg_sync_buffer.html">ogg_sync_buffer()</a>. The buffer
|
|
Chris@1
|
26 is then filled up to the requested size with new input, and
|
|
Chris@1
|
27 ogg_sync_wrote() is called to advance the fill pointer by however
|
|
Chris@1
|
28 much data was actually available.</p>
