       "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
