- * Test Name: utime04
- *
- * Test Description:
- * Verify that the system call utime() successfully sets the modification
- * and access times of a file to the time specified by times argument, if
- * the times argument is not null, and the user ID of the process is "root".
- *
- * Expected Result:
- * utime succeeds returning zero and sets the access and modification
- * times of the file to that specified by the times argument.
- *
- * Algorithm:
- * Setup:
- * Setup signal handling.
- * Create temporary directory.
- * Pause for SIGUSR1 if option specified.
- *
- * Test:
- * Loop if the proper options are given.
- * Execute system call
- * Check return code, if system call failed (return=-1)
- * Log the errno and Issue a FAIL message.
- * Otherwise,
- * Verify the Functionality of system call
- * if successful,
- * Issue Functionality-Pass message.
- * Otherwise,
- * Issue Functionality-Fail message.
- * Cleanup:
- * Print errno log and/or timing stats if options given
- * Delete the temporary directory created.
- *
- * Usage: <for command-line>
- * utime04 [-c n] [-e] [-f] [-i n] [-I x] [-p x] [-t]
- * where, -c n : Run n copies concurrently.
- * -e : Turn on errno logging.
- * -f : Turn off functionality Testing.
- * -i n : Execute test n times.
- * -I x : Execute test for x seconds.
- * -P x : Pause for x seconds between iterations.
- * -t : Turn on syscall timing.
- *
- * History
- * 07/2001 John George
- * -Ported
- *
- * Restrictions:
- * This test should be run by 'super-user' (root) only.
+/*\
+ * [Description]
*
+ * Verify that the system call utime() successfully changes the last
+ * access and modification times of a file to the values specified by
+ * times argument, under the following constraints:
+ * - The times argument is not NULL.
+ * - The user ID of the process is "root".
