* Verify that,

* 1. path is NULL, EFAULT would return.
|

|
|
* 2. Too many symbolic links were encountered in translating path,
|
||

|
* ELOOP would return.
|
||
|
|
* 3. path is too long, ENAMETOOLONG would return.
|
||
|
|
* 4. The file referred to by path does not exist, ENOENT would return.
|
||
|
|
* 5. A component of the path prefix of path is not a directory,
|
||
|
|
* ENOENT would return.
