       XSendExtensionEvent - send input extension events to a client


       #include <X11/extensions/XInput.h>

                                   XDevice *device,
                                   Window destination,

              Specifies the connection to the X server.

              Specifies the device from which the events are to be

              Specifies the window the event is to be sent to. You can
              pass window id, PointerWindow,or InputFocus.

              Specifies a Boolean value that is either True or False.

              Specifies the count of XEventClasses in event_list.

              Specifies the list of event selections to be used.

              Specifies a pointer to the event that is to be sent.


           The XSendExtensionEvent request identifies the destination
           window, determines which clients should receive the specified
           events, and ignores any active grabs. This request requires you
           to pass an event class list. For a discussion of the valid
           event class names, see XOpenDevice(3) This
           request uses the w argument to identify the destination window
           as follows:
             * If w is PointerWindow,the destination window is the window
               that contains the pointer.
             * If w is InputFocusand if the focus window contains the
               pointer,the destination window is the window that contains
               the pointer; otherwise, the destination window is the focus

           To determine which clients should receive the specified events,
           XSendExtensionEventuses the propagate argument as follows:
             * If event_list is the empty set,the event is sent to the
               client that created the destination window. If that client
               no longer exists,no event is sent.
             * If propagate is False,the event is sent to every client
               selecting on destination any of the eventtypes specified by
               the event_list array.
             * If propagate is Trueand no clients have selected on
               destination any ofthe events specified by the event_list
               array,the destination is replaced with theclosest ancestor
               of destination for which some client has selected atype
               specified by the event-list array and for which no
               interveningwindow has that type in
               itsdo-not-propagate-mask. If no such window exists or if
               the window isan ancestor of the focus window and
               InputFocuswas originally specifiedas the destination, the
               event is not sent to any clients. Otherwise, the event is
               reported to every client selecting on the finaldestination
               any of the events specified in the event_list array.

           The event in the XEventstructure must be one of the events
           defined by the input extension (or a BadValueerror results) so
           that the X server can correctly byte-swapthe contents as
           necessary. The contents of the event areotherwise unaltered and
           unchecked by the X server except to force send_event to Truein
           the forwarded event and to set the serial number in the event

           XSendExtensionEventreturns zero if the conversion to wire
           protocol format failedand returns nonzero
           otherwise.XSendExtensionEventcan generate BadClass, BadDevice,
           BadValue, and BadWindow errors.


                  An invalid device was specified. The specified device
                  does not exist or has not been opened by this client via
                  XOpenInputDevice. This error may also occur if the
                  specified device is the X keyboard or X pointer device.

                  Some numeric value falls outside the range of values
                  accepted by the request. Unless a specific range is
                  specified for an argument, the full range defined by the
                  argument's type is accepted. Any argument defined as a
                  set of alternatives can generate this error.

                  A value for a Window argument does not name a defined
