19 *    TEST IDENTIFIER	: getrusage02
20 *
21 *    EXECUTED BY	: anyone
22 *
23 *    TEST TITLE	: Tests for error conditions

26 *
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 *	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.
