     NAME
          XmAddProtocolCallback - a  VendorShell  function  that  adds
          client callbacks for a protocol.



     SYNOPSIS
          #include <Xm/Xm.h>
          #include <X11/Protocols.h>

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

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



     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  will  be 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 cast to Atom).

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

          closureSpecifies  the  client  data  to  be  passed  to  the
                 callback when it is invoked.
