SYNOPSIS

#include <Xm/Xm.h>
#include <Xm/Protocols.h>
void XmAddProtocolCallback (shell, property, protocol, callback,
closure)
Widgetshell;
Atomproperty;

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. 

shellSpecifies the widget with which the protocol property is associated. 

propertySpecifies the protocol property. 

protocolSpecifies the protocol Atom (or an int type cast to Atom). 

callbackSpecifies the procedure to call when a protocol message is received. 

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