+<h1>ov_pcm_seek_page_lap</h1>
+
+<p><i>declared in "vorbis/vorbisfile.h";</i></p>
+
+<p>Seeks to the closest page preceding the specified location (in pcm
+samples) within the physical bitstream. This variant of <a
+href="ov_pcm_seek_page.html">ov_pcm_seek_page</a> also automatically
+crosslaps the transition from the previous playback position into the
+new playback position in order to eliminate clicking and boundary
+discontinuities. Otherwise, usage and behavior is identical to <a
+href="ov_pcm_seek_page.html">ov_pcm_seek_page</a>.
+
+<p>This function is faster than <a
+href="ov_pcm_seek_lap.html">ov_pcm_seek_lap</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>ov_pcm_seek_page_lap 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>ov_pcm_seek_page_lap will lap between logical stream links of
+differing numbers of channels. Any extra channels from the origin of
+the seek are ignored; playback of these channels simply ends. Extra
+channels at the destination are lapped from silence.
+ov_pcm_seek_page_lap will also lap between logical stream links of
+differing sample rates. In this case, the sample rates are ignored
+(no implicit resampling is done to match playback). It is up to the
+application developer to decide if this behavior makes any sense in a
+given context; in practical use, these default behaviors perform
+sensibly.
+
+<p>This function only works for seekable streams.

+<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_EOF - Indicates stream is at end of file immediately after a seek
+ (making crosslap impossible as there's no preceeding decode state to crosslap).
+ </li>
+ <li>OV_EBADLINK - Invalid stream section supplied to libvorbisfile, or the requested link is corrupt.
+ </li>
+ </ul></li>
