          #include <Xm/Protocols.h>
          void XmAddProtocolCallback(
          Widget shell,
          Atom property,

     VERSION
          This page documents Motif 2.1.

     DESCRIPTION
          XmAddProtocolCallback adds client callbacks for a protocol.
          It checks if the protocol is registered, and if it is not,
          calls XmAddProtocols. It then adds the callback to the
          internal list. These callbacks are called when the
          corresponding client message is received.

          XmAddWMProtocolCallback is a convenience interface.  It
          calls XmAddProtocolCallbackwith the property value set to
          the atom returned by interning WM_PROTOCOLS.

          shell     Specifies the widget with which the protocol
                    property is associated

          property  Specifies the protocol property

          protocol  Specifies the protocol Atom

          callback  Specifies the procedure to call when a protocol
                    message is received

          closure   Specifies the client data to be passed to the
                    callback when it is invoked
