I'm trying to make a preference for my protocol following the
readme.developer, and some examples in the src. The preference is based
on the tcp port. Ethereal crashes whenever I change the port to the
default port(global_myprot_tcp_port). However, it works just fine after
it crashed, e.g, ethereal close after crashing, then I open ethereal,
the port that I changed has been saved and applied. Any idea? Following
is the code of reg_handoff which has pref part in it. Thanks
*
void proto_reg_handoff_myprot(void)
{
static int myprot_prefs_initialized = FALSE;
dissector_handle_t myprot_handle;
if (!myprot_prefs_initialized) {
myprot_handle = create_dissector_handle(dissect_myprot,
proto_myprot);
myprot_prefs_initialized = TRUE;
} else {
dissector_delete("tcp.port", myprot_tcp_port, myprot_handle);
}
myprot_tcp_port = global_myprot_tcp_port;
dissector_add("tcp.port", myprot_tcp_port, myprot_handle);
}*
