Could you explain what is the difference with buffered_file.c?
I am fixing problems on buffered_file, and having something that copies
lot of code from there makes me nervous.

typedef ssize_t (BufferedPutFunc)(void *opaque, const void *data, size_t size);

There are not so much types for a write function that the 1st element is
one opaque :p
