| 20 | <p>This function synchronizes the ogg_sync_state struct to the next ogg_page. |
|---|
| 21 | <p>This is useful when seeking within a bitstream. ogg_sync_pageseek will synchronize to the next page in the bitstream and return information about how many bytes we advanced or skipped in order to do so. |
