26  *
27  *    AUTHOR		: sowmya adiga<sowmya.adiga@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 munlockall(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  *        Execute system call
43  *	  Check return code, if system call failed (return=-1)
44  *	  Log the errno and Issue a FAIL message.
45  *	  Otherwise, Issue a PASS message.
46  *
47  * 	Cleanup:
48  * 	  Print errno log and/or timing stats if options given
49  *
50  * USAGE:  <for command-line>
51  *  munlockall01 [-c n] [-e] [-i n] [-I x] [-p x] [-t]
52  *		where,		-c n : Run n copies concurrently
53  *	               		-e   : Turn on errno logging.
54  *				-h   : Show this help screen
55  *				-i n : Execute test n times.
56  *				-I x : Execute test for x seconds.
57  *				-p   : Pause for SIGUSR1 before starting
58  *                      	-P x : Pause for x seconds between iterations.
59  *                       	 t   : Turn on syscall timing.
60  *
61  * RESTRICTIONS
62  * Must be root/superuser to run it.
