   2  * DIRENT.H (formerly DIRLIB.H)
   3  *
   4  * by M. J. Weinstein   Released to public domain 1-Jan-89
   5  *
   6  * Because I have heard that this feature (opendir, readdir, closedir)
   7  * it so useful for programmers coming from UNIX or attempting to port
   8  * UNIX code, and because it is reasonably light weight, I have included
   9  * it in the Mingw32 package. I have also added an implementation of
  10  * rewinddir, seekdir and telldir.
