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.

NAGZILLAC(1) General Commands Manual NAGZILLAC(1)
NAME
nagzillac - jabber relay bot client
SYNOPSIS
nagzillac type^JID^message
DESCRIPTION
This manual page documents briefly the nagzillac command.
nagzillac is the client for nagzilla that takes the data you hand it as argument and sends it over to the nagzilla daemon that will send
the message along.
OPTIONS
nagzillac only takes one options that consists of three arguments. They are seperated by the carret character(`^'), although the last argu-
ment may contain carrets without any troubles. Here is an explenation of the different parts:
type This is the type of the message. It can be either room (which will send the message to a jabber conference room) or chat (target
should be a jabber ID).
JID This is the target for the message. If you choose room type it has to be a conference room name or complete ID. A single room with-
out any @ in it will get sent to the configured conference server. If you choose the chat type the JID has to be the jabber ID of
the user to receive the message, either just the user part which will get added the jabber server as domain part, or a full jabber
ID.
message
The final part is the message that will get sent. At the moment it will be put into the body as plain text. Please notice that you
will have to quote or escape special characters in the message like white space.
FILES
/etc/nagzillac/nagzillac.cfg
The configuration file for the nagzilla client. Please see the comments in the file for informations on what to tweak.
EXAMPLE
The following sends a chat message to the rhonda user on the default server:
nagzillac "chat^rhonda^hi there"
This will send a message to a conference room on a different server:
nagzillac "room^monitor@jabber.doma.in^alert - do something"
