| <h1>ov_pcm_seek_page</h1> |
| |
| <p><i>declared in "ivorbisfile.h";</i></p> |
| |
| <p>Seeks to the closest page preceding the specified location (in pcm samples) within the physical bitstream. This function only works for seekable streams. |
| <p>This function is faster than <a href="ov_pcm_seek.html">ov_pcm_seek</a> because the function can begin decoding at a page boundary rather than seeking through any remaining samples before the specified location. However, it is less accurate. |
| <p>This also updates everything needed within the |
| decoder, so you can immediately call <a href="ov_read.html">ov_read()</a> and get data from |
| the newly seeked to position. |

| <h3>Parameters</h3> |
| <dl> |
| <dt><i>vf</i></dt> |
| <dd>A pointer to the OggVorbis_File structure--this is used for ALL the externally visible libvorbisidec |
| functions.</dd> |
| <dt><i>pos</i></dt> |
| <dd>Position in pcm samples to seek to in the bitstream.</dd> |
| </dl> |
| |
| |
| <h3>Return Values</h3> |
| <blockquote> |
| <li> |
| 0 for success</li> |
| |
| <li> |
| nonzero indicates failure, described by several error codes:</li> |
| <ul> |
| <li>OV_ENOSEEK - Bitstream is not seekable. |
| </li> |
| <li>OV_EINVAL - Invalid argument value. |
| </li> |
| <li>OV_EREAD - A read from media returned an error. |
| </li> |
| <li>OV_EFAULT - Internal logic fault; indicates a bug or heap/stack |
| corruption. |
| </li> |
| <li>OV_EBADLINK - Invalid stream section supplied to libvorbisidec, or the requested link is corrupt. |
| </li> |
| </ul></blockquote> |
