Hello,

I have the following question:

Is it possible to define far pointers in djgpp
as I have done in the following example with MSVC++?
And:
If so, which command line parameters do I have to
specify? (e.g.: gcc -v example.c -o example )
Thank you in advance. JSchumann

#include <dos.h>

void main( void )
{
   void far *p;   /* define pointer */
   unsigned int seg_val;
   unsigned int off_val;

   p = _fmalloc( 100 );         /* example for initialisation of p:
allocate memory */

   seg_val = _FP_SEG( p );      /* get segment- and offset-address */
   off_val = _FP_OFF( p );

   printf("Pointer: %Fp\n" ,p);
   printf("Segment: %.4X\n",seg_val);
   printf("Offset : %.4X\n",off_val);

   _ffree(p);   /* free memory */
}
