I found out inside the FAQ that the Macro MK_FP in djgpp can accomplish a
pointer conversion. But what about the reciprocal of that?
^
|_____________ did i spell it right?
#include <sys/nearptr.h>
#include <crt0.h>

 void * MK_FP (unsigned short seg, unsigned short ofs)
       {
         if ( !(_crt0_startup_flags & _CRT0_FLAG_NEARPTR) )
           if (!__djgpp_nearptr_enable ())
             return (void *)0;
         return (void *) (seg*16 + ofs + __djgpp_conventional_base);
       }


Thanks
