NAME

XmSetProtocolHooks -- A VendorShell function that allows preactions
and postactions to be executed when a protocol message is received
from MWM

SYNOPSIS

#include <Xm/Xm.h>
#include <Xm/Protocols.h>
void XmSetProtocolHooks(
Widget shell,
Atom property,
Atom protocol,
XtCallbackProc prehook,
XtPointer pre_closure,
XtCallbackProc posthook,
XtPointer post_closure);

DESCRIPTION

XmSetProtocolHooks is used by shells that want to have preactions and
postactions executed when a protocol message is received from MWM.
Since there is no guaranteed ordering in execution of event handlers
or callback lists, this allows the shell to control the flow while
leaving the protocol manager structures opaque.

XmSetWMProtocolHooks is a convenience interface. It calls
XmSetProtocolHooks 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

prehook Specifies the procedure to call before calling entries on
the client callback list

pre_closure
Specifies the client data to be passed to the prehook when
it is invoked

posthook Specifies the procedure to call after calling entries on
the client callback list

post_closure
Specifies the client data to be passed to the posthook when
it is invoked
