You could also exploit the queueing behavior of fifos. Or you could use sockets.
I think mutexes,fifos and sockets are both IPC methods.Most generally are there any specific way to do same things instead fifos, pipes and sockets?

Sockets.socketPair(3kaya)				       Kaya module reference					 Sockets.socketPair(3kaya)

NAME
Sockets::socketPair - Create a joined pair of sockets SYNOPSIS
Pair<Socket, Socket> socketPair( ) DESCRIPTION
This function creates a pair of sockets that can be used for bi-directional communication. The most common use of this is for setting up communications between a process and its Posix.fork(3kaya) ()ed child - each process closes one of the sockets after the fork. sockets = socketPair(); pid = fork(); if (pid == 0) { // child process close(sockets.fst); // do something } else { close(sockets.snd); // do something else } AUTHORS
