| * Test Description: |
| * 1. Verify that the system call utime() fails to set the modification |
| * and access times of a file to the current time, under the following |
| * constraints, |
| * - The times argument is null. |
| * - The user ID of the process is not "root". |
| * 2. Verify that the system call utime() fails to set the modification |
| * and access times of a file if the specified file doesn't exist. |
| * 3. Verify that the system call utime() fails to set the modification |
| * and access times of a file to the current time, under the following |
| * constraints, |
| * - The times argument is not null. |
| * - The user ID of the process is not "root". |
| * 4. Verify that the system call utime() fails to set the modification |
| * and access times of a file that resides on a read-only file system. |
