Or, at least, it is somewhat similar... Rod Pemberton #include <stdio.h> #include <dpmi.h> __dpmi_regs r; int main(void) { r.x.ax = 0x4300; __dpmi_int (0x2f, &r); if(r.h.al!=0x80) { /* no XMS */ printf("1\n"); } else { /* XMS */ printf("2\n"); r.x.ax = 0x4310; __dpmi_int (0x2f, &r); r.h.ah=0x00; r.x.cs=r.x.es; r.x.ip=r.x.bx; __dpmi_simulate_real_mode_procedure_retf(&r); // __dpmi_simulate_real_mode_procedure_iret(&r); if (r.x.ax==0x0300) { /* OK */ printf("3\n"); } else { /* NG */ printf("4\n"); } } return(0); }
