There is a hook that can be called to allow the UI to update: ui_loop_hook. This function (if non-null) can be called from your target's wait routine. Care should be taken that it is not called too often, though. (Yeah, this all sucks, but it is the best we can do with some hosts/targets.) ui_loop_hook will return non-zero if the UI (Insight in your case) wants to detach from the target. If Control-C works from the command-line, then you're pretty much done, since Insight will call the appropriate target method to do the stop. You cannot use Control-C in a gui: Control-C has always meant "copy" to a gui. You must use the stop button. There is a very complicated methodology that Insight uses right now to deal with target_wait and stops. It is probably needlessly complicated today, but three years ago, it was needed. If you really want the yicky details, take a peek at the comments in gdbtk-hooks.c near x_event (). Good luck. Keith
