When is the preference variable updated?

[Paul Offord <Paul.Offord () advance7 com>]

Hi,

Frankly I feel a bit stupid asking this but I've been trying to figure it out for about 6 hours and I think I need 
help.  I have a dissector which I register like this:

static int tmsvc_port = 0;

void
proto_register_tmsvc(void)
{
    module_t *tmsvc_module;

    proto_tmsvc = proto_register_protocol("TM Syncro Service",
                                          "TmSyncro",
                                          "tmsvc");

    tmsvc_module = prefs_register_protocol(proto_tmsvc, NULL);

    prefs_register_uint_preference(tmsvc_module, "port",
                                   "TmSyncro service port",
                                   "When set to a value greater than 0 the TmSyncro service is started and accessible 
via the port number"
                                   10,
                                   &tmsvc_port);

}

Immediately after the prefs_register_uint_preference call I check the tmsvc_port value and its still 0 (and I've tried 
other initialisation values and they remain unchanged).  I was expecting tmsvc_port to be set to the value I last set 
by editing the preferences through the Wireshark menu system.

If I check with Menu -> Edit -> Preferences -> Protocols -> TmSyncro sure enough the value I last set is there.

When does my variable get updated?  Or alternatively, how can I retrieve the saved preference value?

Thanks and regards...Paul
