Read an event from the <em>pDev</em> device. If the event is a motion event, enqueue it with the <em>motion</em> function. Otherwise, check for special keys with the <em>checkspecial</em> function and enqueue the event with the <em>enqueue</em> function. The <em>block</em> type is passed to the functions so that they may block SIGIO handling as appropriate to the caller of this function. </td>
