| /* |
| * Test Name: utime01 |
| * |
| * Test Description: |
| * Verify that the system call utime() successfully sets the modification |
| * and access times of a file to the current time, if the times argument |
| * is 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 the current time. |
| * |
| * 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> |
| * utime01 [-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. |
