21 * NAME
22 * rename10
23 *
24 * DESCRIPTION
25 * This test will verify that rename(2) syscall fails with ENAMETOOLONG
26 * and ENOENT
27 *
28 * ALGORITHM
29 * Setup:
30 * Setup signal handling.
31 * Create temporary directory.
32 * Pause for SIGUSR1 if option specified.
33 * create the "old" file
34 *
35 * Test:
36 * Loop if the proper options are given.
37 * 1. rename the "old" to the "new" file
38 * verify rename() failed with error ENAMETOOLONG
39 *
40 * 2. "new" path contains a directory that does not exist
41 * rename the "old" to the "new"
42 * verify rename() failed with error ENOENT
43 * Cleanup:
44 * Print errno log and/or timing stats if options given
45 * Delete the temporary directory created.*
46 *
47 * USAGE
48 * rename10 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
49 * where, -c n : Run n copies concurrently.
50 * -e : Turn on errno logging.
51 * -i n : Execute test n times.
52 * -I x : Execute test for x seconds.
53 * -P x : Pause for x seconds between iterations.
54 * -t : Turn on syscall timing.
55 *
56 * HISTORY
57 * 07/2001 Ported by Wayne Boyer
58 *
59 * RESTRICTIONS
60 * None.
