18 * Test Description:
19 * Verify that,
20 * 1. path is NULL, EFAULT would return.
21 * 2. Too many symbolic links were encountered in translating path,
22 * ELOOP would return.
23 * 3. path is too long, ENAMETOOLONG would return.
24 * 4. The file referred to by path does not exist, ENOENT would return.
25 * 5. A component of the path prefix of path is not a directory,
26 * ENOENT would return.
