I have seen the trigraphs on msdn and ??? is not defined there.
the file where this code is from is vstgui.cpp
Code:
LRESULT CALLBACK MouseProc (int nCode, WPARAM wParam, LPARAM lParam)
{
if (nCode < 0)
return CallNextHookEx (MouseHook, nCode, wParam, lParam);
if (wParam == 522)
{
MOUSEHOOKSTRUCT* struct2 = (MOUSEHOOKSTRUCT*) lParam;
if (struct2->hwnd == ???)
{
return -1;
}
}
return CallNextHookEx (MouseHook, nCode, wParam, lParam);
}
Since this is pretty official stuff i cant believe the programmer just forgot to fill it.
