XSelectInput(3)			XLIB FUNCTIONS		       XSelectInput(3)

NAME
       XSelectInput - select input events

SYNTAX
       int XSelectInput(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 interested 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:

       o    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.

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

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

       o    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.

DIAGNOSTICS
       BadWindow A value for a Window argument does not	name a defined Window.
