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

* - Colin Peters <colin@bird.fu.is.saga-u.ac.jp>
