Ring of Processes When N processes in a ring are up and ready, Process 0 sends a message to be received by Process 1, and so on, to back to Process 0 and done. Whenever a process sends or receives a message, it prints its process # (N), "the message", and "sent" or "received". For nproc = 2, the following figure below shows the ring of 2 processes where each circle is a process and each square is a pipe shared by two processes. //ring.c int fd[2]: pipe(fd): dup2(fd[0], 0): dup2(fd[1], 1): close(fd[0]): close(fd[1]): for (I = 1: i
