- *    TEST IDENTIFIER   : fdatasync01
- *
- *    EXECUTED BY       : Any user
- *
- *    TEST TITLE        : Basic test for fdatasync(2)
- *
- *    TEST CASE TOTAL   : 1
- *
- *    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
- *	This is a Phase I test for the fdatasync(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.
- *	  Create a temp directory and cd to it
- *	  Initialize filename and open it in write mode for each child process.
- *
- *	Test:
- *	 Loop if the proper options are given.
- *	  Execute system call
- *	  Check return code, if system call failed (return=-1)
- *		Issue FAIL message with errno.
- *	  Otherwise, Issue PASS message.
- *
- *	Cleanup:
- *	  Print errno log and/or timing stats if options given
- *	  Remove temporary directory and all files in it.
- *
- * USAGE:  <for command-line>
- *  fdatasync01 [-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.
