Note that utime() is the only function [I believe] where a structure is passed into the system without having been obtained by a prior library call. This makes it "special". I would guess that this is why AT&T never put it into a header file. --Donald Lewine uunet!dg!lewine Volume-Number: Volume 20, Number 153
