/*
|
|
* 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.
|
