     30  *
     31  *    SIGNALS
     32  *	Uses SIGUSR1 to pause before test if option set.
     33  *	(See the parse_opts(3) man page).
     34  *
     35  *    DESCRIPTION
     36  *	This test case checks whether sysfs(2) system call  returns
     37  *	appropriate error number for invalid
     38  *	option.
     39  *
     40  *	Setup:
     41  *	  Setup signal handling.
     42  *	  Pause for SIGUSR1 if option specified.
     43  *
     44  *	Test:
     45  *	  Loop if the proper options are given.
     46  *	  Execute system call with invaid  option parameter
     47  *
     48  *	  Check return code, if system call fails with errno == expected errno
     49  *		Issue syscall passed with expected errno
     50  *	  Otherwise,
     51  *	  Issue syscall failed to produce expected errno
     52  *
     53  *	Cleanup:
     54  *	  Do cleanup for the test.
     55  *
     56  * USAGE:  <for command-line>
     57  * sysfs04  [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-f] [-p]
     58  * where:
     59  *	-c n : run n copies simultaneously
     60  *	-e   : Turn on errno logging.
     61  *	-i n : Execute test n times.
     62  *	-I x : Execute test for x seconds.
     63  *	-p   : Pause for SIGUSR1 before starting
     64  *	-P x : Pause for x seconds between iterations.
     65  *	-t   : Turn on syscall timing.
     66  *
     67  *RESTRICTIONS:
     68  *No libc or glibc support
