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 propa-
       gates 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, ConfigureRequest, 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.
