\fBXmActivateProtocol\fP \(em A VendorShell function that activates a protocol

#include <Xm/Protocols\&.h>

.SH "DESCRIPTION"
.PP
\fBXmActivateProtocol\fP activates a protocol\&. It
updates the handlers and the \fIproperty\fP if
the \fIshell\fP 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 \fIprotocol\fP to be in one of two states: active or
inactive\&. If the \fIprotocol\fP is active and the \fIshell\fP is realized,
the \fIproperty\fP contains the \fIprotocol\fP \fBAtom\fP\&.
If the \fIprotocol\fP is inactive, the \fBAtom\fP is not present in
the \fIproperty\fP\&.
.PP
\fBXmActivateWMProtocol\fP is a convenience interface\&.
It calls \fBXmActivateProtocol\fP
with the property value set to the atom returned by
interning \fBWM_PROTOCOLS\fP\&.
