in reply to Re^4: Highly efficient variable-sharing among processes
in thread Highly efficient variable-sharing among processes
But the processes sharing memory do not have to communicate anything between them; the memory remains shared and readable by one without the other being in any way aware of the read.
One process has to fill the memory with data in order the other could read it. The fact that it doesn't aware about reads is not significant, communication doesn't have to be two way. My TV can receive signal without making TV tower aware of that, it's still communication.
