XSelectInput(3X11)
X11R6
NAME
  XSelectInput - select input events

SYNOPSIS
  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 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:

    ·  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.

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