- * NAME
- *	setitimer03.c
+/*\
+ * [Description]
  *
- * DESCRIPTION
- *	setitimer03 - check that a setitimer() call fails as expected
- *		      with incorrect values.
- *
- * ALGORITHM
- *	loop if that option was specified
- *	allocate needed space and set up needed values
- *	issue the system call
- *	check the errno value
- *	  issue a PASS message if we get EINVAL
- *	otherwise, the tests fails
- *	  issue a FAIL message
- *	  break any remaining tests
- *	  call cleanup
- *
- * USAGE:  <for command-line>
- *  setitimer03 [-c n] [-e] [-i n] [-I x] [-p x] [-t]
- *     where,  -c n : Run n copies concurrently.
- *             -e   : Turn on errno logging.
- *	       -i n : Execute test n times.
- *	       -I x : Execute test for x seconds.
- *	       -P x : Pause for x seconds between iterations.
- *	       -t   : Turn on syscall timing.
- *
- * HISTORY
- *	03/2001 - Written by Wayne Boyer
- *
- * RESTRICTIONS
- *	none
+ * Verify that setitimer(2) syscall fails with EINVAL when given
+ * an invalid timer.
