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_propa-
       gate 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, Configur-
	    eRequest, 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.

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