| 2 | * This is a native test to explore how the readdir() family works. |
---|
| 3 | * Newlib supports the following readdir() family members: |
---|
| 4 | * |
---|
| 5 | * closedir() - |
---|
| 6 | * readdir() - |
---|
| 7 | * scandir() - |
---|
| 8 | * opendir() - |
---|
| 9 | * rewinddir() - |
---|
| 10 | * telldir() - BSD not in POSIX |
---|
| 11 | * seekdir() - BSD not in POSIX |
---|
| 12 | * |
---|
| 13 | * |
---|
| 14 | * seekdir() takes an offset which is a byte offset. The Linux |
---|
| 15 | * implementation of this appears to seek to the ((off/DIRENT_SIZE) + 1) |
---|
| 16 | * record where DIRENT_SIZE seems to be 12 bytes. |
---|
| 17 | * |
