| 21 | <p>The application is not required to make use of all of the samples
|

| 22 | made available to it by one call to this function before it continues to
|

| 23 | decode. Use <a href="vorbis_synthesis_read.html">vorbis_synthesis_read</a>
|
|---|
| 24 | to inform the decoder of how many samples were actually used. Any
|
|---|
| 25 | unused samples will be included in the buffers output by the next call
