*
* 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.
