Details | Compare with Previous | View Log


/*
 *  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.
 *
 *
