+ * 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.
+ *
