These structures are declared in "vorbis/vorbisfile.h" and "vorbis/codec.h". <p> <p>When using libvorbisfile, it's not necessary to know about most of the contents of these data structures, but it may be helpful to understand what they contain. <br><br> <table border=1 color=black width=50% cellspacing=0 cellpadding=7> <tr bgcolor=#cccccc> <td><b>datatype</b></td> <td><b>purpose</b></td> </tr> <tr valign=top> <td><a href="OggVorbis_File.html">OggVorbis_File</a></td> <td>This structure represents the basic file information.
