21 * NAME
22 * msgrcv03.c
23 *
24 * DESCRIPTION
25 * msgrcv03 - test for EINVAL error
26 *
27 * ALGORITHM
28 * create a message queue with read/write permissions
29 * loop if that option was specified
30 * call msgrcv() using two different invalid cases
31 * check the errno value
32 * issue a PASS message if we get EINVAL
33 * otherwise, the tests fails
34 * issue a FAIL message
35 * call cleanup
36 *
37 * USAGE: <for command-line>
38 * msgrcv03 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
39 * where, -c n : Run n copies concurrently.
40 * -e : Turn on errno logging.
41 * -i n : Execute test n times.
42 * -I x : Execute test for x seconds.
43 * -P x : Pause for x seconds between iterations.
44 * -t : Turn on syscall timing.
