I've just made some quick checks. This _may_ work. The problem is that
GetKeyboardState possible does not work at all for console apps :-) If
it works it is great, because in _theory_ it can report the status of
all keys at once.

#include <windows.h>
#include <stdio.h>

int main() {
  ::Sleep(3000);
  char buffer[256];
  ::GetKeyboardState( reinterpret_cast<PBYTE>(buffer) );
  for(unsigned i = 0; i < 256; ++i)
    printf("%X\n", buffer[i]);
}

Note that it waits for 3 seconds before testing the keyboard. Diff its
output and play with virtual key codes ;-)
