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. 
21
22<p>
23The general proceedure is to request a pointer into an internal 
24<a href="ogg_sync_state.html">ogg_sync_state</a> buffer by calling 
25<a href="ogg_sync_buffer.html">ogg_sync_buffer()</a>. The buffer
26is then filled up to the requested size with new input, and 
27ogg_sync_wrote() is called to advance the fill pointer by however
28much data was actually available.</p>
