I second the motion!  Benefits include:
	(1)  Easier coding
	(2)  Cleaner coding
	(3)  Portable coding
	(4)  Faster operation due to buffering

Of course virtually ALL the UNIX System V Release 2 utilities have
been so converted in the BRL UNIX System V emulation for 4.2BSD
(out of necessity).  If AT&T wants `em they can have `em.  I also
previously posted a UNIX System V edition of the directory access
library routines.  They should be added to the standard C library!
