When I wanted to load Vesa's VbeInfoBlock with DJGPP-compiler, I used to do
following code:

void GETVIB(void)
{
    int seg, off;
    if (vib) delete vib;
    vib=0;
    __dpmi_regs r;
    /* RM seg:offset for transfer buffer */
    seg = (__tb & 0xffff0000) >> 4;            // This means a segment in
absolute 16-bit
    off = (__tb & 0x0000ffff);                       // flat real-mode
address-space.
    /* request VBE information */
    _farpokel(_dos_ds, __tb, 0x32454256);    // Signature "VBE2"
    r.x.di = off;
    r.x.es = seg;
    r.x.ax = 0x4f00;
    __dpmi_int(0x10, &r);                            // Make 16-bit real
mode interrupt call
    if ((r.x.ax==0x004f) &&(_farpeekw(_dos_ds, __tb+4)>=0x0200))
    {
        vib=new VbeInfoBlock;
        dosmemget(__tb, sizeof(struct VbeInfoBlock), vib);    // Copy VIB to
memory that

// C++ can use.
    }
}

Now... How I do same thing with Microsoft Visual C++?
