19 *    TEST IDENTIFIER	: capset01
20 *
21 *    EXECUTED BY	: anyone
22 *
23 *    TEST TITLE	: Basic test for capset(2)
24 *
25 *    TEST CASE TOTAL	: 1
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 *	This is a Phase I test for the capset(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 *	  call capget() to save the current capability data
41 *
42 * 	Test:
43 *	 Loop if the proper options are given.
44 * 	  call capset() with the saved data
45 *	  if return value == 0
46 *		Test passed
47 *	  Otherwise
48 *		Test failed
49 *
50 * 	Cleanup:
51 * 	  Print errno log and/or timing stats if options given
52 *
53 * USAGE:  <for command-line>
54 * capset01 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-f] [-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.
64 *
65 * CHANGES:
66 *  2005/01/01: add an hint to a possible solution when test fails
67 *              - Ricky Ng-Adam <rngadam@yahoo.com>
