| 21 | * Test Name: utime05 |
| 22 | * |
| 23 | * Test Description: |
| 24 | * Verify that the system call utime() successfully sets the modification |
| 25 | * and access times of a file to the value specified by the times argument |
| 26 | * under the following constraints, |
| 27 | * - The times argument is not 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: |
subrata_modak | 4bb656a | 2009-02-26 12:02:09 +0000 | [diff] [blame] | 32 | * utime succeeds returning zero and sets the access and modification |
plars | 865695b | 2001-08-27 22:15:12 +0000 | [diff] [blame] | 33 | * times of the file to that specified by the times argument. |
| 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) |
subrata_modak | 56207ce | 2009-03-23 13:35:39 +0000 | [diff] [blame] | 45 | * Log the errno and Issue a FAIL message. |

plars | 865695b | 2001-08-27 22:15:12 +0000 | [diff] [blame] | 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 | * utime05 [-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. |
