|
|
* 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.
