| /* |
| * Test Description: |
| * Verify that, |
| * 1. Creat a directory and open it, then delete the directory, ENOENT would |
| * return. |
| * 2. File descriptor does not refer to a directory, ENOTDIR would return. |
| * 3. Invalid file descriptor fd, EBADF would return. |
| * 4. Argument points outside the calling process's address space, EFAULT |
| * would return. |
| * |
| * PS: |
| * This file is for readdir(2) and the other files(readdir01.c and |
| * readdir02.c) are for readdir(3). |
