21 * NAME
22 * rename05
23 *
24 * DESCRIPTION
25 * This test will verify that rename(2) fails with EISDIR
26 *
27 * ALGORITHM
28 * Setup:
29 * Setup signal handling.
30 * Create temporary directory.
31 * Pause for SIGUSR1 if option specified.
32 * create the "old" file and the "new" directory
33 * rename the "old" file to the "new" directory
34 *
35 * Test:
36 * Loop if the proper options are given.
37 * verify rename() failed and returned EISDIR
38 *
39 * Cleanup:
40 * Print errno log and/or timing stats if options given
41 * Delete the temporary directory created.
42 *
43 * USAGE
44 * rename05 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
45 * where, -c n : Run n copies concurrently.
46 * -e : Turn on errno logging.
47 * -i n : Execute test n times.
48 * -I x : Execute test for x seconds.
49 * -P x : Pause for x seconds between iterations.
50 * -t : Turn on syscall timing.
51 *
52 * HISTORY
53 * 07/2001 Ported by Wayne Boyer
54 *
55 * RESTRICTIONS
56 * None.
