Mike is suggesting you not use vorbisfile at all. Take a look at 
examples/decoder_example.c in the libvorbis source distribution. This 
shows how to use the lower level api.

You can just 'ogg_sync_wrote()' whatever bytes you were able to read and 
let it take care of buffering the data, and then go as far as you can 
down the call sequence before returning and waiting for more data.
