| 16 | <h1>General Functions</h1> |
|---|
| 17 | <p>Libogg contains several functions which are generally useful when using Ogg streaming, whether encoding or decoding. |
|---|
| 18 | <p> |
|---|
| 19 | All the <b>libogg</b> specific functions are declared in "ogg/ogg.h". |
|---|
| 20 | <p> |
|---|
| 21 | <p>These functions can be used to manipulate some of the basic elements of Ogg - streams and pages. Streams and pages are important during both the encode and decode process. |
