/* For once, the VAC compiler/library did a nice thing.
* The file handle used by the C runtime is the same one
* returned by the OS when you call DosOpen(). This means
* that you can take an OS HFILE and use it with C file
* functions. The only caveat is that you have to call
* _setmode() first to initialize some junk. This is
* immensely useful because I did not have a clue how to
* implement this function otherwise. The windows folks
* took the source from the Microsoft C library source, but
* IBM wasn't kind enough to ship the source with VAC.
* On second thought, the needed function could probably
* be gotten from the OS/2 GNU library source, but the
* point is now moot.
