/***
*doscalls.h - functions declarations for OS/2 function calls

* Copyright (c) 1986-1992, Microsoft Corporation. All rights reserved.
*
*Purpose:
* Function declarations to provide strong type checking on
* arguments to OS/2 function calls used by the C run-time.
* Only those functions which are referenced in C sources
* are included in this file. This saves compilation time,
* reduces the amount of memory needed by the compiler, and
* prevents recompilation due to changes that do not directly
* affect the C run-time. This file should be updated when a
* "C" module is changed to use a new OS/2 function call.
