- * NAME
- *	uname02.c
- *
- * DESCRIPTION
- *	uname02 - call uname() with an invalid address to produce a failure
- *
- * ALGORITHM
- *	loop if that option was specified
- *	issue the system call
- *	check the errno value
- *	  issue a PASS message if we get EFAULT - errno 14
- *	otherwise, the tests fails
- *	  issue a FAIL message
- *	  break any remaining tests
- *	  call cleanup
- *
- * USAGE:  <for command-line>
- *  uname02 [-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
- *	07/2001 John George
