Question: Consider an interprocess-communication that uses mailboxes: // send msg to Process Id, TOID mailbox: receive (FromID, msg) // receive msg from process id, FromID

Consider an interprocess-communication that uses mailboxes: // send msg to Process Id, TOID mailbox: receive (FromID, msg) // receive msg from process id, FromID mailbox: send (TOID, msg) Is it possible for a process to wait to get a message from any one of a number of processes? If your answer is yes, write a program pseudo code that does so. Now, consider the case that we add a new mailbox primitive: mailbox: empty (FromID) // returns false if no msg in mailbox, // return true otherwise Use it to write pseudo code for a program that waits for a message from any one of a number of processes. Assume there are total of n processes, numbered: 0 through (n-1).
