| /* |
| * Description: |
| * 1) create a directory tstdir1, create a file under it. |
| * call rmdir(tstdir1), verify the return value is -1 |
| * and the errno is ENOTEMPTY. |
| * 2) create a directory with long path, call rmdir(tstdir1), |
| * verify the return value is -1 and the errno is ENAMETOOLONG. |
| * 3) pass a pathname containing non-exist directory component |
| * to rmdir(), verify the return value is -1 and the errno |
| * is ENOENT. |
| * 4) pass a pathname containing a file component to rmdir(), |
| * verify the return value is -1 and the errno is ENOTDIR. |
| * 5) attempt to pass an invalid pathname with an address |
| * pointing outside the address space of the process, as the |
| * argument to rmdir(), verify the return value is -1 and |
| * the errno is EFAULT. |
| * 6) attempt to pass an invalid pathname with NULL, as the |
| * argument to rmdir(), verify the return value is -1 and |
| * the errno is EFAULT. |
| * 7) pass a pathname with too many symbolic links to rmdir(), |
| * verify the return value is -1 and the errno is ELOOP. |
| * 8) pass a pathname which refers to a directory on a read-only |
| * file system to rmdir(), verify the return value is -1 and |
| * the errno is EROFS. |
| * 9) pass a pathname which is currently used as a mount point |
| * to rmdir(), verify the return value is -1 and the errno is |
| * EBUSY. |
