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. <p> <br><br> <table border=0 color=black cellspacing=0 cellpadding=7> <tr bgcolor=#cccccc> <td> <pre><b> int ov_pcm_seek_page(OggVorbis_File *vf,ogg_int64_t pos); </b></pre> </td> </tr> </table> <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 libvorbisfile 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> <ul> <li>0 for success</li> <li> nonzero indicates failure, described by several error codes: <ul> <li>OV_ENOSEEK - Bitstream is not seekable. </li> <li>OV_EINVAL - Invalid argument value; possibly called with an OggVorbis_File structure that isn't open. </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 libvorbisfile, or the requested link is corrupt. </li> </ul></li> </ul></blockquote> <br><br> <hr noshade> <table border=0 width=100%> <tr valign=top> <td><p class=tiny>copyright © 2007 Xiph.org</p></td> <td align=right><p class=tiny><a href="http://www.xiph.org/ogg/vorbis/">Ogg Vorbis</a></p></td> </tr><tr> <td><p class=tiny>Vorbisfile documentation</p></td> <td align=right><p class=tiny>vorbisfile version 1.2.0 - 20070723</p></td> </tr> </table> </body> </html>
