NAME
       XSelectInput - select input events

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

ARGUMENTS
       Specifies the connection to the X server.  Specifies the event mask.  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: 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  SubstructureRedirect-
       Mask.   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
       A value for a Window argument does not name a defined Window.
