19 *    TEST IDENTIFIER	: timer_create03
20 *
21 *    EXECUTED BY	: anyone
22 *
23 *    TEST TITLE	: Basic test for timer_create(2)
24 *
25 *    TEST CASE TOTAL	: 3
26 *
27 *    AUTHOR		: Aniruddha Marathe <aniruddha.marathe@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 timer_create(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 with different notification types for
44 *	 clock ID CLOCK_MONOTONIC
45 *	 Check return code, if system call failed (return=-1)
46 *		Log the errno and Issue a FAIL message.
47 *	 Otherwise, Issue a PASS message.
48 *
49 * 	Cleanup:
50 * 	  Print errno log and/or timing stats if options given
51 *
52 * USAGE:  <for command-line>
53 * timer_create03 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-p]
54 * where:
55 * 	-c n : Run n copies simultaneously.
56 *	-e   : Turn on errno logging.
57 *	-i n : Execute test n times.
58 *	-I x : Execute test for x seconds.
59 *	-p   : Pause for SIGUSR1 before starting
60 *	-P x : Pause for x seconds between iterations.
61 *	-t   : Turn on syscall timing.
62 *
63 *RESTRICTIONS:
64 * None
