In article <1661@apt.UUCP> brian@apt.UUCP (Brian Litzinger) writes
of needing to creating asynchronous children and not having his
process table filled up.

Try orphaning your children (sounds mean, doesn't it).  Just do
something like:


void create_an_orphaned_process()
{
	int	pid1, pid2;


	if ((pid1 = fork()) < 0)
		end_all_life("no need to live");

	if (pid1 == 0) {

		/* the child -- it'll fork and die */

		if (pid2 = fork()) < 0)
			end_all_thought_of_life("why me");

		if (pid2 == 0) {
			exec("some grandchild program");
			end_all_sentient_life("shouldn't get here");
		} else
			exit(0);	/* the child is no longer needed */
	}

	return;	/* the original process goes on its merry way */

} /* end function */
