-<h1>ov_crosslap()</h1>
-
-<p><i>declared in "vorbis/vorbisfile.h";</i></p>
-
-<p>ov_crosslap overlaps and blends the boundary at a transition
-between two separate streams represented by separate <a
-href="OggVorbis_File.html">OggVorbis_File</a> structures. For lapping
-transitions due to seeking within a single stream represented by a
-single <a href="OggVorbis_File.html">OggVorbis_File</a> structure,
-consider using the lapping versions of the <a
-href="seeking.html">vorbisfile seeking functions</a> instead.
-
-<p>ov_crosslap is used between the last (usually ov_read) call on
-the old stream and the first ov_read from the new stream. Any
-desired positioning of the new stream must occur before the call to
-ov_crosslap() as a seek dumps all prior lapping information from a
-stream's decode state. Crosslapping does not introduce or remove any
-extraneous samples; positioning works exactly as if ov_crosslap was not
-called.
-
-<p>ov_crosslap will lap between streams of differing numbers of
-channels. Any extra channels from the old stream are ignored; playback
-of these channels simply ends. Extra channels in the new stream are
-lapped from silence. ov_crosslap will also lap between streams 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.

-<h3>Parameters</h3>
-<dl>
-<dt><i>old</i></dt>
-<dd>A pointer to the OggVorbis_File structure representing the origin stream from which to transition playback.</dd>
-
-<dt><i>new</i></dt>
-<dd>A pointer to the OggVorbis_File structure representing the stream with which playback continues.</dd>
-</dl>

-<h3>Return Values</h3>
-<blockquote>
-<dl>
-<dt>OV_EINVAL</dt>
- <dd>crosslap called with an OggVorbis_File structure that isn't open.</dd>
-<dt>OV_EFAULT</dt>
- <dd>internal error; implies a library bug or external heap corruption.</dd>
-<dt>OV_EREAD</dt>
- <dd> A read from media returned an error.</dd>
-<dt>OV_EOF</dt>
- <dd>indicates stream <tt>vf2</tt> is at end of file, or that <tt>vf1</tt> is at end of file immediately after a seek (making crosslap impossible as there's no preceding decode state to crosslap).</dd>
-<dt><i>0</i></dt>
- <dd>success.</dd>
