Hasn't anyone ever felt the need for an fwrite interface ?
I was looking at a perl clone of (John Haugh ? can't remember)'s
utmp-dead-process reaper, and looks to me that it's not strictly
speaking possible.

(this goes through each utmp entry and modifies it in place if the
 user on that line no longer exists -- mainly intended for pty
 sessions, but also useful for "ct" dialback sessions)

What I mean is, that 

	with stdio:	can't.  no interface to fwrite.

	without stdio:	well, there's no guarantee that stdio's fseek
			necessarily calls lseek at that moment, so if
			it doesn't, then I need a syslseek().

Have I got the wrong end of the stick ?
