22 * NAME
23 * 	sigpending02.c
24 *
25 * DESCRIPTION
26 * 	Test to see the the proper errors are returned by sigpending
27 *$
28 * ALGORITHM
29 * 	test 1:
30 * 	Call sigpending(sigset_t*=-1), it should return -1 with errno EFAULT
31 *
32 * USAGE:  <for command-line>
33 *         -c n    Run n copies concurrently
34 *         -e      Turn on errno logging
35 *         -f      Turn off functional testing
36 *         -h      Show this help screen
37 *         -i n    Execute test n times
38 *         -I x    Execute test for x seconds
39 *         -p      Pause for SIGUSR1 before starting
40 *         -P x    Pause for x seconds between iterations
41 *         -t      Turn on syscall timing
