XmAddProtocolCallback(3X)
OSF/Motif
NAME
  XmAddProtocolCallback - A VendorShell function that adds 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;
	  XtCallbackProc callback;
	  XtPointer closure;

  void XmAddWMProtocolCallback (shell, protocol, callback, closure)
	  Widget shell;
	  Atom protocol;
	  XtCallbackProc callback;
	  XtPointer 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 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 WM_PROTOCOLS.

  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.

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