Hello again, Thank you both. I have not looked at waitqueues before, but will do it now. The reason I currently need a signal, is that I want the recv-call to return and *_stop can't do that. However, maybe putting it in a waitqueue will work. -Kristian -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
