21 * Test Name: utime02
22 *
23 * Test Description:
24 * Verify that the system call utime() successfully sets the modification
25 * and access times of a file to the current time, under the following
26 * constraints,
27 * - The times argument is null.
28 * - The user ID of the process is not "root".
29 * - The file is owned by the user ID of the process.
30 *
31 * Expected Result:
32 * utime succeeds returning zero and sets the access and modification
33 * times of the file to the current time.
34 *
35 * Algorithm:
36 * Setup:
37 * Setup signal handling.
38 * Create temporary directory.
39 * Pause for SIGUSR1 if option specified.
40 *
41 * Test:
42 * Loop if the proper options are given.
43 * Execute system call
44 * Check return code, if system call failed (return=-1)
45 * Log the errno and Issue a FAIL message.
46 * Otherwise,
47 * Verify the Functionality of system call
48 * if successful,
49 * Issue Functionality-Pass message.
50 * Otherwise,
51 * Issue Functionality-Fail message.
52 * Cleanup:
53 * Print errno log and/or timing stats if options given
54 * Delete the temporary directory created.
55 *
56 * Usage: <for command-line>
57 * utime02 [-c n] [-e] [-f] [-i n] [-I x] [-p x] [-t]
58 * where, -c n : Run n copies concurrently.
59 * -e : Turn on errno logging.
60 * -f : Turn off functionality Testing.
61 * -i n : Execute test n times.
62 * -I x : Execute test for x seconds.
63 * -P x : Pause for x seconds between iterations.
64 * -t : Turn on syscall timing.
