DirectInput -> Keyboard -> GetDeviceState

[Arjen Nienhuis]

The MapVirtualKey in GetDeviceState is not "the way to do it". It does 
not map VK_?? to DIK_??. I don't know why it does work most of the time.
"ptr[i] = 0x80; ptr[i + 0x80] = 0x80;" gave double key events in a game 
I have.

The correct way to convert the keys is by this table (attachment).
I made this table by pressing all the keys on my keyboard, and record 
the keycodes.

The code I wrote for this function is:

static HRESULT WINAPI SysKeyboardAImpl_GetDeviceState(
         LPDIRECTINPUTDEVICE2A iface, DWORD len, LPVOID ptr
)
{
     DWORD i;
     memset( ptr, 0, len );
     if (len != 256)
     {
         WARN("whoops, got len %ld?\n", len);
         return DI_OK;
     }

for (i = 0; i < (sizeof(vk_to_dik) / sizeof(vk_to_dik[0])); i++)
       if (GetAsyncKeyState( vk_to_dik[i][0] ) & 0x8000)
         ((LPBYTE)ptr)[ vk_to_dik[i][1] ] = 0x80;

return DI_OK;
}

Is there an array_size() macro in wine?
where should I put this table?
Any other comments about my first usefull (at least for me) wine code?
