kill() function problem in client-server ipc message using 2 FIFOs

I want to have a message send & receive through 2 uni-direction FIFO

Flow of data

FIFO1

stdin--->parent(client) writefd--->FIFO1-->child(server) readfd

FIFO2

child(server) writefd2---->FIFO2--->parent(client) readfd2--->stdout

I need to have boundary structed message mesg_len+mesg_type+mesg_data

The function is that if user input "Knock Knock" on stdin, which directs to client, client send this message to server through FIFO1, server compares the string, if matches with "Knock Knock", then server reply message "Who's there?" to client through FIFO2, and client write this message to the stdout.
