                                           int *count);
 
 display
        Specifies the connection to the X server.
 
 window
        Specifies the window whose dont-propagate-list is to be
        queried or modified.
 
 event_list
        Specifies a pointer to a list of event classes.
 
 mode
        Specifies the mode.You can pass AddToList, or
        DeleteFromList.
 
 count
        Specifies the number of event classes in the list.
 

DESCRIPTION

 The XChangeDeviceDontPropagateList request modifies the list of
 events that should not be propagated to ancestors of the event
 window. This request allows extension events to be added to or
 deleted from that list. By default, all events are propagated
 to ancestor windows. Once modified, the list remains modified
 for the life of the window. Events are not removed from the
 list because the client that added them has terminated.
 
 Suppression of event propagation is not allowed for all input
 extension events. If a specified event class is one that cannot
 be suppressed, a BadClass error will result. Events that can be
 suppressed include DeviceKeyPress, DeviceKeyRelease,
 DeviceButtonPress, DeviceButtonRelease, DeviceMotionNotify,
 ProximityIn, and ProximityOut.
 
 XChangeDeviceDontPropagateList can generate a BadDevice,
 BadClass, or BadValue error.
 
 The XGetDeviceDontPropagateList request queries the list of
 events that should not be propagated to ancestors of the event
 window.
 
 XGetDeviceDontPropagateList can generate a BadClass or
 BadWindow error.
 

DIAGNOSTICS

 BadDevice
        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 some
        other client has caused the specified device to become
        the X keyboard or X pointer device via the
        XChangeKeyboardDevice or XChangePointerDevice requests.
 
 BadValue
        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.
 
 BadWindow
        An invalid window id was specified.
 
 BadClass
        An invalid event class was specified.
