Yes, but it means that I can't decide to replace all uses
of write() with pwrite() for instance. At one stage I

This lack of clarity is one of the things I don't like.

More that bugs or inconsistency in the user provided VIO functions
look like libsndfile bugs.

You shouldn't have too.

Anything that you can do with 16 bit PCM WAV files that you can't
do with FLAC (and libsndfile doesn't say there is an error) is
probably a bug.

It should for all the standard file formats. If it doesn't for
FLAC then thats a bug that I would try to fix or make sure that
libsndfile notifies the client program that something has gone
wrong.
