int pascal PostMessage(HWND hWnd, WORD msg, WORD wParam, DWORD lParam)
   <MS Windows eq>

  This function places a message in the system message queue. This is
a way of asynchronously passing a message to a window or to the
system. Eventually, calling GetMessage() will retrieve this message
and calling DispatchMessage() will send the message to the specified
window.

Parameters
  hWnd is the handle of the window which should receive this message.
   If hWnd is NULLHWND, then DispatchMessage() will make the
   determination of who gets this message. If hWnd is 0xFFFF, then the
   message will be posted to every top level window currently defined.
  msg is the message code which should be passed to the window.
  wParam and lParam contain the argument data for the message.

Returns
  TRUE if the message was posted, FALSE if not.
