List-Id: General discussion about Adeos List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: adeos-main@gna.org Hello everybody, I'm using an IPIPE domain for a cyclic realtime task and I have a cyclic kernel timer applet running in the default domain. This two processes now share a common resource. So I have to use some locking method, that ensures, that if the process with the lower priority (e. g. the kernel timer) holds the lock and the process with the higher priority (RT task) is scheduled, the first one is scheduled again until it releases the lock. In ADEOS there is a adeos_mutex_lock() call seeming to do exactly what I want. Unfortunately IPIPE doesn't seem to have such a call. How do I solve the problem with IPIPE? Thanks a lot, Florian
