     27  *    AUTHOR		: Aniruddha Marathe <aniruddha.marathe (at) 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_REALTIME
     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_create02 [-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
