| * Test Description: |
| * Verify that, |
| * 1. getdents() fails with -1 return value and sets errno to EBADF |
| * if file descriptor fd is invalid. |
| * 2. getdents() fails with -1 return value and sets errno to EINVAL |
| * if result buffer is too small. |
| * 3. getdents() fails with -1 return value and sets errno to ENOTDIR |
| * if file descriptor does not refer to a directory. |
| * 4. getdents() fails with -1 return value and sets errno to ENOENT |
| * if there is no such directory. |
