- *
- * TEST IDENTIFIER : munlock02
- *
- * EXECUTED BY : root / superuser
- *
- * TEST TITLE : Test for checking basic error conditions for
- * munlock(2)
- *
- * TEST CASE TOTAL : 2
- *
- * AUTHOR : Nirmala Devi Dhanasekar <nir...@wi...>
- *
- * SIGNALS
- * Uses SIGUSR1 to pause before test if option set.
- * (See the parse_opts(3) man page).
- *
- * DESCRIPTION
- * Check for basic errors returned by munlock(2) system call.
- *
- * Verify that munlock(2) returns -1 and sets errno to
- *
- * 1) ENOMEM - If process exceed maximum number of locked pages.
- *
- * Setup:
- * Setup signal handling.
- * Pause for SIGUSR1 if option specified.
- *
- * Test:
- * Loop if the proper options are given.
- * Do necessary setup for each 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>
- * munlock02 [-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
- * Test must run as root.
