21 * NAME
22 * msgctl03.c
23 *
24 * DESCRIPTION
25 * msgctl03 - create a message queue, then issue the IPC_RMID command
26 *
27 * ALGORITHM
28 * create a message queue
29 * loop if that option was specified
30 * call msgctl() with the IPC_RMID command
31 * check the return code
32 * if failure, issue a FAIL message and break remaining tests
33 * otherwise,
34 * if doing functionality testing
35 * issue an IPC_STAT on the queue that was just removed
36 * if the call fails
37 * issue a PASS message
38 * otherwise
39 * issue a FAIL message
40 * else issue a PASS message
41 * call cleanup
42 *
43 * USAGE: <for command-line>
44 * msgctl03 [-c n] [-f] [-I x] [-P x] [-t]
45 * where, -c n : Run n copies concurrently.
46 * -f : Turn off functionality Testing.
47 * -I x : Execute test for x seconds.
48 * -P x : Pause for x seconds between iterations.
49 * -t : Turn on syscall timing.
50 *
51 * HISTORY
52 * 03/2001 - Written by Wayne Boyer
53 *
54 * RESTRICTIONS
55 * This test does not support looping.
