- *
- *    TEST TITLE        : Basic test for flock(2)
- *
- *    TEST CASE TOTAL   : 3
- *
- *    AUTHOR            : Vatsal Avasthi <vatsal.avasthi@wipro.com>
- *
- *    SIGNALS
- *      Uses SIGUSR1 to pause before test if option set.
- *      (See the parse_opts(3) man page).
- *
- *    DESCRIPTION
- * 	Test to verify flock(2) succeeds with all kind of locks.
- *	Intends to provide a limited exposure of system call.
- *    $
- *	Setup:
- *        Setup signal handling.
- *        Pause for SIGUSR1 if option specified.
- *        Create a temporary directory and chdir to it.
- * 	  Create a temporary file
- *
- *	Test:
- *	Loop if proper options are given.
- *		Execute system call
- *		Check return code, if system call failed (return == -1)
- *				Log the error number and issue a FAIL message
- *		otherwise issue a PASS message
- *
- *      Cleanup:
- *        Print errno log and/or timing stats if options given
- *	  Deletes temporary directory.
- *
- * USAGE:  <for command-line>
- *      flock01 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-f] [-p]
- *                      where,  -c n : Run n copies concurrently.
- *                              -f   : Turn off functional testing
- *    				-e   : Turn on errno logging.
- *                              -h   : Show 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.
