Problem 4-5. Asynchronous Message Passing (2 points) Readers/Writers Problem. Based on the monitor RW_Controller defined in Figure 5.5, Andrews' book, page 216, develop a server process for read/write control using asynchronous message passing. Suppose we have k reader processes and n-k writer processes, which are defined as follows: type op_kind - enum (READ REQ, READ_DONE, WRITE REQ, WRITE DONE) chan request (int clientID, op_kind kind) ; chan replytnO process Reader[i -0 to k-1] process Writerli -k to n-l while (true) ( while (true) ( send request (i, READ-REQ ); receive reply [ i ] ( ) ; reading send request (i, READ_DONE) receive replyti]0 send request(i, WRITE_REQ) receive reply [ i ] ( ) ; writing send request(i, WRITE_DONE) receive reply[i]0 Problem 4-5.
