 *
 *    TEST IDENTIFIER	: munlockall01
 *
 *    EXECUTED BY	: root / superuser
 *
 *    TEST TITLE	: Basic test for munlockall(2)
 *
 *    TEST CASE TOTAL	: 1
 *
 *    AUTHOR		: sowmya adiga<sowmya.adiga@wipro.com>
 *
 *    SIGNALS
 * 	Uses SIGUSR1 to pause before test if option set.
 * 	(See the parse_opts(3) man page).
 *
 *    DESCRIPTION
 *	This is a phase I test for the munlockall(2) system call.
 *	It is intended to provide a limited exposure of the system call.
 *
 * 	Setup:
 *	  Setup signal handling.
 *	  Pause for SIGUSR1 if option specified.
 *
 * 	Test:
 *        Execute system call
 *	  Check return code, if system call failed (return=-1)
 *	  Log the errno and Issue a FAIL message.
 *	  Otherwise, Issue a PASS message.
 *
 * 	Cleanup:
 * 	  Print errno log and/or timing stats if options given
 *
 * USAGE:  <for command-line>
 *  munlockall01 [-c n] [-e] [-i n] [-I x] [-p x] [-t]
 *		where,		-c n : Run n copies concurrently
 *	               		-e   : Turn on errno logging.
 *				-h   : Show this help screen
 *				-i n : Execute test n times.
 *				-I x : Execute test for x seconds.
 *				-p   : Pause for SIGUSR1 before starting
 *                      	-P x : Pause for x seconds between iterations.
 *                       	 t   : Turn on syscall timing.
 *
 * RESTRICTIONS
 * Must be root/superuser to run it.
