27  *    AUTHOR		: Saji Kumar.V.R <saji.kumar@wipro.com>
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.
