- * 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
- * -Ported
- *
- * Restrictions
- * none
