*Purpose: |

|
* Defines the structs and unions used for the direct DOS interface |
8 |
|
* routines; includes macros to access the segment and offset |
9 |
|
* values of far pointers, so that they may be used by the routines; and |
10 |
|
* provides function prototypes for direct DOS interface functions. |
