|
|
* DESCRIPTION
|
|
*
|
|
* This file is for support of program manager under NT Windows.
|
|
* This file is/was ported from pmdos.asm (program manager).
|
|
* It was in x86 asm code, and now is in ansi C.
|
|
* Some functions will be removed, due to they are only needed
|
|
* by DOS Windows.
|
|
*
|
|
* MODIFICATION HISTORY
|
|
* Initial Version: x/x/90 Author Unknown, since he didn't feel
|
|
* like commenting the code...
|
|
*
|
|
* NT 32b Version: 1/9/91 Jeff Pack
|
|
* Intitial port to begin.
|
|
*
|
|
* WARNING: since this is NOT for DOS, I'm making it soley 32bit aware.
|
|
* Following functions not ported
|
|
* IsRemovable() is in pmcomman.c (already ifdef'd in asm code)
|
|
* IsRemote() is in pmcomman.c (ditto!)
