<h1>ov_info</h1>

<p><i>declared in "vorbis/vorbisfile.h";</i></p>

<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 vorbisfile

struct should be passed to all the vorbisfile functions.</b></dd>
<dt><i>i</i></dt>
<dd>Link to the desired logical bitstream.  For nonseekable files, this argument is ignored.  To retrieve the <a href="vorbis_info.html">vorbis_info</a> struct for the current bitstream, this parameter should be set to -1.</dd>
</dl>


<h3>Return Values</h3>
<blockquote>
<li>Returns the vorbis_info struct for the specified bitstream.  Returns vorbis_info for current bitstream if the file is nonseekable or i=-1.</li>
<li>NULL if the specified bitstream does not exist or the file has been initialized improperly.</li>
