21 * Test Name: chmod01
22 *
23 * Test Description:
24 * Verify that, chmod(2) succeeds when used to change the mode permissions
25 * of a file.
26 *
27 * Expected Result:
28 * chmod(2) should return 0 and the mode permissions set on file should match
29 * the specified mode.
30 *
31 * Algorithm:
32 * Setup:
33 * Setup signal handling.
34 * Create temporary directory.
35 * Pause for SIGUSR1 if option specified.
36 *
37 * Test:
38 * Loop if the proper options are given.
39 * Execute system call
40 * Check return code, if system call failed (return=-1)
41 * Log the errno and Issue a FAIL message.
42 * Otherwise,
43 * Verify the Functionality of system call
44 * if successful,
45 * Issue Functionality-Pass message.
46 * Otherwise,
47 * Issue Functionality-Fail message.
48 * Cleanup:
49 * Print errno log and/or timing stats if options given
50 * Delete the temporary directory created.
51 *
52 * Usage: <for command-line>
53 * chmod01 [-c n] [-e] [-f] [-i n] [-I x] [-P x] [-t]
54 * where, -c n : Run n copies concurrently.
55 * -e : Turn on errno logging.
56 * -f : Turn off functionality Testing.
57 * -i n : Execute test n times.
58 * -I x : Execute test for x seconds.
59 * -P x : Pause for x seconds between iterations.
60 * -t : Turn on syscall timing.
61 *
62 * HISTORY
63 * 07/2001 Ported by Wayne Boyer
64 *
65 * RESTRICTIONS:
66 * None.
