- *dos.h - definitions for MS-DOS interface routines
- *
- * Copyright (c) 1985-1997, Microsoft Corporation. All rights reserved.
- *
- *Purpose:
- * Defines the structs and unions used for the direct DOS interface
- * routines; includes macros to access the segment and offset
- * values of far pointers, so that they may be used by the routines; and
- * provides function prototypes for direct DOS interface functions.
