19 *    TEST IDENTIFIER	: timer_create04
20 *
21 *    EXECUTED BY	: anyone
22 *
23 *    TEST TITLE	: Test checking for basic error conditions for
24 *    			  timer_create(2)
25 *
26 *    TEST CASE TOTAL	: 8
27 *
28 *    AUTHOR		: Aniruddha Marathe <aniruddha.marathe@wipro.com>
29 *
30 *    SIGNALS
31 * 	Uses SIGUSR1 to pause before test if option set.
32 * 	(See the parse_opts(3) man page).
33 *
34 *    DESCRIPTION
35 *    	This test case check whether timer_create(2) returns appropriate error
36 *    	value for invalid parameter
37 *
38 * 	Setup:
39 *	 Setup signal handling.
40 *	 Pause for SIGUSR1 if option specified.
41 *
42 * 	Test:
43 *	 Loop if the proper options are given.
44 *	 For case 7 set event parameter as bad pointer
45 *	 for case 8 set returned timer ID parameter as bad pointer
46 *	 Execute system call with invalid parameter
47 *	 Check return code, if system call fails with errno == expected errno
48 * 	 	Issue syscall passed with expected errno
49 *	 Otherwise, Issue syscall failed to produce expected errno
50 *
51 * 	Cleanup:
52 * 	 Print errno log and/or timing stats if options given
53 *
54 * USAGE:  <for command-line>
55 * timer_create04 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-p]
56 * where:
57 * 	-c n : run n copies simultaneously
58 *	-e   : Turn on errno logging.
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 * RESTRICTIONS:
66 * None
