declared in "vorbis/vorbisfile.h";

Returns the total pcm samples of the physical bitstream or a specified logical bitstream.

int64_t ov_pcm_total(OggVorbis_File *vf,int i);

Parameters

vf

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

i

Link to the desired logical bitstream. To retrieve the total pcm samples for the entire physical bitstream, this parameter should be set to -1.

Return Values

OV_EINVAL means that the argument was invalid. In this case, the requested bitstream did not exist or the bitstream is unseekable.

total length in pcm samples of content if i=-1.

length in pcm samples of logical bitstream if i=1 to n.
