16 <h1>Base Data Structures</h1>
17 <p>There are several data structures used to hold file and bitstream information during libvorbisfile decoding. These structures are declared in "vorbis/vorbisfile.h" and "vorbis/codec.h".
19 <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.

29 <td>This structure represents the basic file information. It contains
30 a pointer to the physical file or bitstream and various information about that bitstream.</td>
33 <td><a href="vorbis_comment.html">vorbis_comment</a></td>
34 <td>This structure contains the file comments. It contains
35 a pointer to unlimited user comments, information about the number of comments, and a vendor description.</td>
38 <td><a href="vorbis_info.html">vorbis_info</a></td>
39 <td>This structure contains encoder-related information about the bitstream. It includes encoder info, channel info, and bitrate limits.</td>

43 <td>This structure contains pointers to the application-specified file manipulation routines set for use by <a href="ov_open_callbacks.html">ov_open_callbacks()</a>. See also the <a href="callbacks.html">provided document on using application-provided callbacks instead of stdio</a>.</td>
