I'd be curious as to why that happens. As fd's 0, 1, and 2 are in use,
the sequence
close(3);
if (open("/dev/null", O_RDONLY) != 3
|| pipe(pipe3fd) < 0
|| close(3)
|| (dupped = dup(pipe3fd[1])) != 3)
{
fprintf(stderr, "Unable to reserve file descriptor 3.\n");
cannot fail. Can you reproduce the failure running the program by itself?
If that's possible, truss can reveal what's going on.
