       XmAddProtocolCallback  —  A VendorShell function that adds client callbacks for a protocol
       "XmAddProtocolCallback" "VendorShell functions" "XmAddProtocolCallback" "protocols"

SYNOPSIS

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

       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
