21 * NAME
22 * signal02.c
23 *
24 * DESCRIPTION
25 * signal02 - Test that we get an error using illegal signals
26 *
27 * ALGORITHM
28 * loop if that option was specified
29 * issue the system call
30 * check the return value
31 * if return value != -1
32 * issue a FAIL message, break remaining tests and cleanup
33 * if we get an EINVAL
34 * issue a PASS message
35 * else
36 * issue a FAIL message, break remaining tests and cleanup
37 * call cleanup
38 *
39 * USAGE: <for command-line>
40 * signal02 [-c n] [-e] [-i n] [-I x] [-p x] [-t]
41 * where, -c n : Run n copies concurrently.
42 * -e : Turn on error 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.
47 *
48 * History
