          client callbacks for a protocol

     SYNOPSIS
          #include <Xm/Xm.h>
          #include <Xm/Protocols.h>

          void XmAddProtocolCallback (shell, property, protocol, callback, closure)
               Widget      shell;
               Atom        property;
               Atom        protocol;
               XtCallbackProccallback;
               XtPointer   closure;

          void XmAddWMProtocolCallback (shell, protocol, callback, closure)
               Widget      shell;
               Atom        protocol;

     VERSION
          This page documents version 1.2 of the Motif library.

     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 XmAddProtocolCallback with the property value set to
          the atom returned by interning WMPROTOCOLS.


          shell  Specifies the widget with which the protocol property
                 is associated.

          property
                 Specifies the protocol property.

          protocol
                 Specifies the protocol Atom (or an int type cast to
                 Atom).

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

          closureSpecifies the client data to be passed to the
