21 * NAME
22 * semget03.c
23 *
24 * DESCRIPTION
25 * semget03 - test for ENOENT error
26 *
27 * ALGORITHM
28 * loop if that option was specified
29 * call semget() with a valid key but with no associated semaphore set
30 * and IPC_CREAT is not asserted
31 * check the errno value
32 * issue a PASS message if we get ENOENT
33 * otherwise, the tests fails
34 * issue a FAIL message
35 * call cleanup
36 *
37 * USAGE: <for command-line>
38 * semget03 [-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.
