I note in the Sender class there is a variable "_wq". What is the role of this variable? And in the IPC, we set it to the sender_list of receiver. Why?

wq is short for wait-queue and it is used during IPC to connect sender and receiver. The queue is prio sorted so that IPCs happen according to their prio. Adam -- Adam adam@os.inf.tu-dresden.de Lackorzynski http://os.inf.tu-dresden.de/~adam/
