16 <h1>Base Data Structures</h1>
|
|
Chris@1
|
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".
|
|
Chris@1
|
18 <p>
|
|
Chris@1
|
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.
