19 *    TEST IDENTIFIER	: munlock01
20 *
21 *    EXECUTED BY	: root / superuser
22 *
23 *    TEST TITLE	: Basic test for munlock(2)
24 *
25 *    TEST CASE TOTAL	: 4
26 *
27 *    AUTHOR		: Nirmala Devi Dhanasekar <nirmala.devi@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 munlock(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
44 *	  Check return code, if system call failed (return=-1)
45 *		Log the errno and Issue a FAIL message.
46 *	  Otherwise, Issue a PASS message.
47 *
48 * 	Cleanup:
49 * 	  Print errno log and/or timing stats if options given
50 *
51 * USAGE:  <for command-line>
52 *  munlock01 [-c n] [-e] [-i n] [-I x] [-p x] [-t]
53 *		where,		-c n : Run n copies concurrently
54 *				-e   : Turn on errno logging.
55 *				-h   : Show this help screen
56 *				-i n : Execute test n times.
57 *				-I x : Execute test for x seconds.
58 *				-p   : Pause for SIGUSR1 before starting
59 *				-P x : Pause for x seconds between iterations.
60 *				-t   : Turn on syscall timing.
61 *
62 * RESTRICTIONS
63 * Must be root/superuser to run it.
