* Description:
|
|
* Verify that,
|
|
* 1) utimes() returns -1 and sets errno to EACCES if times
|
|
* is NULL, the caller's effective user ID does not match
|
|
* the owner of the file, the caller does not have write
|
|
* access to the file, and the caller is not privileged.
|
|
* 2) utimes() returns -1 and sets errno to ENOENT if filename
|
|
* does not exist.
|
|
* 3) utimes() returns -1 and sets errno to EFAULT if filename
|
|
* is NULL.
|
|
* 4) utimes() returns -1 and sets errno to EPERM if times is
|
|
* not NULL, the caller's effective UID does not match the
|
|
* owner of the file, and the caller is not privileged.
|
|
* 5) utimes() returns -1 and sets errno to EROFS if path resides
|
|
* on a read-only file system.
