XSelectInput(3X11)	  XLIB FUNCTIONS       XSelectInput(3X11)


NAME
       XSelectInput - select input events

SYNTAX
       XSelectInput(display, w, event_mask)
	     Display *display;
	     Window w;
	     long event_mask;

ARGUMENTS
       display	 Specifies the connection to the X server.

       event_mask
		 Specifies the event mask.

       w	 Specifies the window whose events you are inter
		 ested in.

DESCRIPTION
       The XSelectInput function requests that the X server
       report the events associated with the specified event
       mask.  Initially, X will not report any of these events.
       Events are reported relative to a window.  If a window is
       not interested in a device event, it usually propagates to
       the closest ancestor that is interested, unless the
       do_not_propagate mask prohibits it.

       Setting the event-mask attribute of a window overrides any
       previous call for the same window but not for other
       clients.	 Multiple clients can select for the same events
       on the same window with the following restrictions:

	   Multiple clients can select events on the same window
	    because their event masks are disjoint.  When the X
	    server generates an event, it reports it to all
	    interested clients.

	   Only one client at a time can select
	    CirculateRequest, ConfigureRequest, or MapRequest
	    events, which are associated with the event mask
	    SubstructureRedirectMask.

	   Only one client at a time can select a ResizeRequest
	    event, which is associated with the event mask
	    ResizeRedirectMask.

	   Only one client at a time can select a ButtonPress
	    event, which is associated with the event mask
	    ButtonPressMask.

       The server reports the event to all interested clients.

       XSelectInput can generate a BadWindow error.
