21 * Test Name: utime04
22 *
23 * Test Description:
24 * Verify that the system call utime() successfully sets the modification
25 * and access times of a file to the time specified by times argument, if
26 * the times argument is not null, and the user ID of the process is "root".
27 *
28 * Expected Result:
29 * utime succeeds returning zero and sets the access and modification
30 * times of the file to that specified by the times argument.
31 *
32 * Algorithm:
33 * Setup:
34 * Setup signal handling.
35 * Create temporary directory.
36 * Pause for SIGUSR1 if option specified.
37 *
38 * Test:
39 * Loop if the proper options are given.
40 * Execute system call
41 * Check return code, if system call failed (return=-1)
42 * Log the errno and Issue a FAIL message.
43 * Otherwise,
44 * Verify the Functionality of system call
45 * if successful,
46 * Issue Functionality-Pass message.
47 * Otherwise,
48 * Issue Functionality-Fail message.
49 * Cleanup:
50 * Print errno log and/or timing stats if options given
51 * Delete the temporary directory created.
52 *
53 * Usage: <for command-line>
54 * utime04 [-c n] [-e] [-f] [-i n] [-I x] [-p x] [-t]
55 * where, -c n : Run n copies concurrently.
56 * -e : Turn on errno logging.
57 * -f : Turn off functionality Testing.
58 * -i n : Execute test n times.
59 * -I x : Execute test for x seconds.
60 * -P x : Pause for x seconds between iterations.
61 * -t : Turn on syscall timing.
62 *
63 * History
64 * 07/2001 John George
65 * -Ported
66 *
67 * Restrictions:
68 * This test should be run by 'super-user' (root) only.
