- *    TEST IDENTIFIER	: sysfs03
- *
- *    EXECUTED BY	: anyone
- *
- *    TEST TITLE	: Basic test for sysfs(2)
- *
- *    TEST CASE TOTAL	: 1
- *
- *    AUTHOR		: Aniruddha Marathe <aniruddha.marathe@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 sysfs(2) system call.
- *    It is intended to provide a limited exposure of the system call.
- *    This testcase tests sysfs(2) for option 3
- *
- *	Setup:
- *	  Setup signal handling.
- *	  Pause for SIGUSR1 if option specified.
- *
- *	Test:
- *	 Loop if the proper options are given.
- *	  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>
- * sysfs03 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-p] [-f]
- * where:
- *	-c n : Run n copies simultaneously
- *	-e   : Turn on errno logging.
- *	-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:
- *There is no glibc or libc support
