     21  * NAME
     22  *	setitimer03.c
     23  *
     24  * DESCRIPTION
     25  *	setitimer03 - check that a setitimer() call fails as expected
     26  *		      with incorrect values.
     27  *
     28  * ALGORITHM
     29  *	loop if that option was specified
     30  *	allocate needed space and set up needed values
     31  *	issue the system call
     32  *	check the errno value
     33  *	  issue a PASS message if we get EINVAL
     34  *	otherwise, the tests fails
     35  *	  issue a FAIL message
     36  *	  break any remaining tests
     37  *	  call cleanup
     38  *
     39  * USAGE:  <for command-line>
     40  *  setitimer03 [-c n] [-e] [-i n] [-I x] [-p x] [-t]
     41  *     where,  -c n : Run n copies concurrently.
     42  *             -e   : Turn on errno logging.
     43  *	       -i n : Execute test n times.
     44  *	       -I x : Execute test for x seconds.
     45  *	       -P x : Pause for x seconds between iterations.
     46  *	       -t   : Turn on syscall timing.
