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.
