     28  *
     29  *    SIGNALS
     30  * 	Uses SIGUSR1 to pause before test if option set.
     31  * 	(See the parse_opts(3) man page).
     32  *
     33  *    DESCRIPTION
     34  *	This is a Phase I test for the getrusage(2) system call.
     35  *	It is intended to provide a limited exposure of the system call.
     36  *
     37  * 	Setup:
     38  * 	  Setup signal handling.
     39  *	  Pause for SIGUSR1 if option specified.
     40  *
     41  * 	Test:
     42  *	 Loop if the proper options are given.
     43  * 	  Execute system call
     44  *	  if return code == 0
     45  *		Test Passed
     46  *	  else
     47  *		Test Failed
     48  *
     49  * 	Cleanup:
     50  * 	  Print errno log and/or timing stats if options given
     51  *
     52  * USAGE:  <for command-line>
     53  *  getrusage01 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-f]
     54  * 			     [-p]
     55  *			where,  -c n : Run n copies concurrently.
     56  *				-e   : Turn on errno logging.
     57  *				-h   : Show help screen
     58  *				-f   : Turn off functional testing
     59  *				-i n : Execute test n times.
     60  *				-I x : Execute test for x seconds.
     61  *				-p   : Pause for SIGUSR1 before starting
     62  *				-P x : Pause for x seconds between iterations.
     63  *				-t   : Turn on syscall timing.
