# DWORD appears to be an :int (32 bits that is, so :int should work well)
# HWND appears to be a :pointer see this thread for why you should not actually read from the value it points to. You may as well just use a :long or :ulong.
# LPDWORD is a pointer (the P standing for pointer)
# LPARAM appears to be a long (hence the L)
# WPARAM appears to be a long (i.e. 64 bits on 64bit OS).
# BOOL is an :int
