XmActivateProtocol — A VendorShell function that activates a protocol "XmActivateProtocol" "VendorShell functions" "XmActivateProtocol" "protocols"
#include <Xm/Protocols.h> void XmActivateProtocol( Widget shell, Atom property, Atom protocol);
XmActivateProtocol activates a protocol. It updates the handlers and the property if the shell is realized. It is sometimes useful to allow a protocol's state information (callback lists, and so on) to persist, even though the client may choose to temporarily resign from the interaction. This is supported by allowing a protocol to be in one of two states: active or inactive. If the protocol is active and the shell is realized, the property contains the protocol Atom. If the protocol is inactive, the Atom is not present in the property.
XmActivateWMProtocol is a convenience interface. It calls XmActivateProtocol with the property value set to the atom returned by interning WM_PROTOCOLS.
