ov_info

declared in "vorbis/vorbisfile.h";

Returns the vorbis_info struct for the specified bitstream. For nonseekable files, always returns the current vorbis_info struct.

vorbis_info *ov_info(OggVorbis_File *vf,int link);

Parameters

vf

A pointer to the OggVorbis_File structure--this is used for ALL the externally visible libvorbisfile functions.

i

Link to the desired logical bitstream. For nonseekable files, this argument is ignored. To retrieve the vorbis_info struct for the current bitstream, this parameter should be set to -1.

Return Values

Returns the vorbis_info struct for the specified bitstream. Returns vorbis_info for current bitstream if the file is nonseekable or i=-1.

NULL if the specified bitstream does not exist or the file has been initialized improperly.
