[net.sources] dup2

jt@druca.UUCP (08/29/83)

Thanks to everyone who answered my query about dup2().  Although some
people had invented their own version of the function, the easiest
solution seemed to be the following:

	dup2(arg1,arg2) is replaced by fcntl(arg1,F_DUPFD, agr2).
	You must use the header file fcntl.h for fcntl().

Thanks again,
