- *
- *    TEST IDENTIFIER   : fdatasync02
- *
- *    EXECUTED BY       : Any user
- *
- *    TEST TITLE        : Checking error conditions for fdatasync(2)
- *
- *    TEST CASE TOTAL   : 2
- *
- *    AUTHOR            : Madhu T L <madhu.tarikere@wipro.com>
- *
- *    SIGNALS
- *      Uses SIGUSR1 to pause before test if option set.
- *      (See the parse_opts(3) man page).
- *
- *    DESCRIPTION
- *      Verify that,
- *      1. fdatasync(2) returns -1 and sets errno to EBADF for invalid
- *	   file descriptor.
- *      2. fdatasync(2) returns -1 and sets errno to EINVAL for file
- *         descriptor to a special file.
- *
- *      Setup:
- *        Setup signal handling.
- *        Set expected errnos for logging
- *        Pause for SIGUSR1 if option specified.
- *
- *      Test:
- *       Loop if the proper options are given.
- *	  Perform testcase specific setup (if needed)
- *        Execute system call
- *        Check return code and error number, if matching,
- *                   Issue PASS message
- *        Otherwise,
- *                   Issue FAIL message
- *	  Perform testcase specific cleanup (if needed)
- *
- *      Cleanup:
- *        Print errno log and/or timing stats if options given
- *
- * USAGE:  <for command-line>
- *  fdatasync02 [-c n] [-e] [-f] [-h] [-i n] [-I x] [-p] [-P x] [-t]
- *		where,  -c n : Run n copies concurrently.
- *			-e   : Turn on errno logging.
- *			-f   : Turn off functional testing
- *			-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.
