/*
* This is a native test to explore how the readdir() family works.
* Newlib supports the following readdir() family members:
*
* closedir() -
* readdir() -
* scandir() -
* opendir() -
* rewinddir() -
* telldir() - BSD not in POSIX
* seekdir() - BSD not in POSIX
*
*
* seekdir() takes an offset which is a byte offset. The Linux
* implementation of this appears to seek to the ((off/DIRENT_SIZE) + 1)
* record where DIRENT_SIZE seems to be 12 bytes.
