21 * NAME
22 * msgsnd03.c
23 *
24 * DESCRIPTION
25 * msgsnd03 - test for EINVAL error
26 *
27 * ALGORITHM
28 * create a message queue with read/write permissions
29 * create a trivial message buffer
30 * loop if that option was specified
31 * call msgsnd() using four different invalid cases
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 * call cleanup
37 *
38 * USAGE: <for command-line>
39 * msgsnd03 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
40 * where, -c n : Run n copies concurrently.
41 * -e : Turn on errno logging.
42 * -i n : Execute test n times.
43 * -I x : Execute test for x seconds.
44 * -P x : Pause for x seconds between iterations.
45 * -t : Turn on syscall timing.
