21 * NAME
22 * rename04
23 *
24 * DESCRIPTION
25 * This test will verify that rename(2) failed when newpath is
26 * a non-empty directory and return EEXIST or ENOTEMPTY
27 *
28 * ALGORITHM
29 * Setup:
30 * Setup signal handling.
31 * Create temporary directory.
32 * Pause for SIGUSR1 if option specified.
33 * create the "old" directory and the "new" directory
34 * create a file uner the "new" directory
35 *
36 * Test:
37 * Loop if the proper options are given.
38 * rename the "old" to the "new" directory
39 * verify rename() failed and returned ENOTEMPTY
40 *
41 * Cleanup:
42 * Print errno log and/or timing stats if options given
43 * Delete the temporary directory created.
44 *
45 * USAGE
46 * rename04 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
47 * where, -c n : Run n copies concurrently.
48 * -e : Turn on errno logging.
49 * -i n : Execute test n times.
50 * -I x : Execute test for x seconds.
51 * -P x : Pause for x seconds between iterations.
52 * -t : Turn on syscall timing.
53 *
54 * HISTORY
55 * 07/2001 Ported by Wayne Boyer
56 *
57 * RESTRICTIONS
58 * None.
