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

#include <Xm/Protocols.h>
void XmAddProtocolCallback(
Widget shell,
Atom property,
Atom protocol,
XtCallbackProc callback,
XtPointer closure);

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.
