FP_OFF
FP_SEG

Usage

   #include <dos.h>
   unsigned FP_OFF(int far *fpointer);
   unsigned FP_SEG(void far *fpointer);

Description

   FP_OFF and FP_SEG are used to split far pointers into their offset and
   segment parts. These functions are implemented as macros.

Example 

   #include <dos.h>
   #include <stdio.h>
   #include <stdlib.h>

   int main()
   {
       char far *p;
       unsigned int segment, offset;
       p = MK_FP(0xb000,0);
       segment = FP_SEG(p);
       offset = FP_OFF(p);
       printf("The mono video segment:offset ");
       printf("is at %04x:%04x \n", segment,offset);
       return EXIT_SUCCESS;
   }

Return Value

   FP_SEG returns the 16-bit segment value of the far pointer. FP_OFF
   returns the 32-bit offset of the far pointer.
