A VendorShell function that activates a protocol
#include <Xm/Protocols.h> void XmActivateProtocol Widget shellAtom propertyAtom 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.
