#include <sys/nearptr.h> // gotta include this

void main()
{

char *screen;  // this is gonna grow up into a pointer to display memory
__djgpp_nearptr_enable();    // turn off memory protection

screen = (char *)(0xa0000 + __djgpp_conventional_base);  // set screen to video 
                                                         // memory base

/* Do whatever ya want with screen here */


__djgpp_nearptr_disable();    // turn memory protection back on
}
