21 * NAME
22 * rename06
23 *
24 * DESCRIPTION
25 * This test will verify that rename(2) failed in EINVAL
26 *
27 * ALGORITHM
28 * Setup:
29 * Setup signal handling.
30 * Create temporary directory.
31 * Pause for SIGUSR1 if option specified.
32 * create the "old" directory
33 * create the "new" directory under the "old" directory
34 *
35 * Test:
36 * Loop if the proper options are given.
37 * rename the "old" to the "new" directory
38 * verify rename() failed and returned EINVAL
39 *
40 * Cleanup:
41 * Print errno log and/or timing stats if options given
42 * Delete the temporary directory created.
43 *
44 * USAGE
45 * rename06 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
46 * where, -c n : Run n copies concurrently.
47 * -e : Turn on errno logging.
48 * -i n : Execute test n times.
49 * -I x : Execute test for x seconds.
50 * -P x : Pause for x seconds between iterations.
51 * -t : Turn on syscall timing.
52 *
53 * HISTORY
54 * 07/2001 Ported by Wayne Boyer
55 *
56 * RESTRICTIONS
57 * None.
