00016 <h1>ov_raw_seek</h1>
00017
00018 <p><i>declared in "vorbis/vorbisfile.h";</i></p>
00019
00020 <p>Seeks to the offset specified (in compressed raw bytes) within the physical bitstream. This function only works for seekable streams.
00021 <p>This also updates everything needed within the
00022 decoder, so you can immediately call <a href="ov_read.html">ov_read()</a> and get data from
00023 the newly seeked to position.
00024 <p>When seek speed is a priority, this is the best seek funtion to use.

00047 <blockquote>
00048 <ul>

00050
00051 <li>
00052 nonzero indicates failure, described by several error codes:
00053 <ul>
00054 <li>OV_ENOSEEK - Bitstream is not seekable.
00055 </li>
00056 <li>OV_EINVAL - Invalid argument value; possibly called with an OggVorbis_File structure that isn't open.
00057 </li>
00058 <li>OV_EREAD - A read from media returned an error.
00059 </li>
00060 <li>OV_EFAULT - Internal logic fault; indicates a bug or heap/stack
00061 corruption.
00062 </li>
00063 <li>OV_EBADLINK - Invalid stream section supplied to libvorbisfile, or the requested link is corrupt.
00064 </li>
