/*

 *  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.

 *

 *
