Re: NetBSD bug/misbehavior in vdprintf

| Is the interface any different for fprintf than dprintf?
fprintf (via the FILE) has a buffer - fprintf copies the (formatted)
data to the buffer, and then writes that. The buffer remains after
the call returns (with or without having actually written anything).
dprintf has just a fd, all it can do is immediately write what it has
been given, if the write fails, for any reason, it fails - there's no
place to keep the data to try again later.
All that said, I see no reason why NetBSD's dprintf() should be different
than anyone else's, and Christos' recent change makes sense to me.
