 +==== Description of setmousequeuestatus ==== 
 +<code c>
 +The setmousequeuestatus function is available in the winbgim
 +implementation of BGI graphics. This function controls whether mouse
 +events of a particular kind are queued for processing. If the status
 +parameter is false, then mouse events of the specified kind are not
 +queued. This means that each time a mouse event of that kind occurs, any
 +previous events of the same kind are deleted. If the status parameter is
 +true, then mouse events of the specified kind are queued, and each call
 +to getmouseclick returns the details about the event at the front of the
 +queue.
 +When a window first opens, queuing is turned off for all events.
