     29  *    SIGNALS
     30  * 	Uses SIGUSR1 to pause before test if option set.
     31  * 	(See the parse_opts(3) man page).
     32  *
     33  *    DESCRIPTION
     34  *	Verify that
     35  *	1) getrusage() fails with errno EINVAL when an invalid value
     36  *	   is given for who
     37  *	2) getrusage() fails with errno EFAULT when an invalid address
     38  *	   is given for usage
     39  *
     40  * 	Setup:
     41  * 	  Setup signal handling.
     42  *	  Pause for SIGUSR1 if option specified.
     43  *
     44  * 	Test:
     45  *	 Loop if the proper options are given.
     46  * 	  Execute system call
     47  *	  if call failed with expected errno,
     48  *		Test Passed
     49  *	  else
     50  *		Test Failed
     51  *
     52  * 	Cleanup:
     53  * 	  Print errno log and/or timing stats if options given
     54  *
     55  * USAGE:  <for command-line>
     56  *  getrusage02 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-f]
     57  * 			     [-p]
     58  *			where,  -c n : Run n copies concurrently.
     59  *				-e   : Turn on errno logging.
     60  *				-h   : Show help screen
     61  *				-f   : Turn off functional testing
     62  *				-i n : Execute test n times.
     63  *				-I x : Execute test for x seconds.
     64  *				-p   : Pause for SIGUSR1 before starting
     65  *				-P x : Pause for x seconds between iterations.
     66  *				-t   : Turn on syscall timing.
