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
