[Users] Re: [Devel] test return code in config file

[Klaus Darilion]

Can this be used to exit from a route block to avoid the workaround 
using flags, e.g.:

route {
  route(1);
  if (retcode == 99) break;
  ...
}

route[1] {
   if (security check fails) {
	return(99);
   }
   ... do some things;
}


Is there a differnce between
   return(0);
and
   break;
?

regards,
klaus
