**     FILE     NAME:       devlib.h
**     SYSTEM   NAME:       
**     ORIGINAL AUTHOR(S):  Paul Lemmers
**     VERSION  NUMBER:     
**     CREATION DATE:       1990/8/14
**
** DESCRIPTION: 
**              Include file for OS/2 device driver functions
**              Do not expect to find a ".lib" file even if the name
**              suggests the existance. The library is a large collection
**              of object files since the link list must decide which and
**              where to link the module. Some parts are resident and
**              others only init time.
