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?

dbus-cleanup-sockets(1) General Commands Manual dbus-cleanup-sockets(1)
NAME
dbus-cleanup-sockets - clean up leftover sockets in a directory
SYNOPSIS
dbus-cleanup-sockets [DIRECTORY]
DESCRIPTION
The dbus-cleanup-sockets command cleans up unused D-Bus connection sockets. See http://www.freedesktop.org/software/dbus/ for more informa-
tion about the big picture.
If given no arguments, dbus-cleanup-sockets cleans up sockets in the standard default socket directory for the per-user-login-session mes-
sage bus; this is usually /tmp. Optionally, you can pass a different directory on the command line.
On Linux, this program is essentially useless, because D-Bus defaults to using "abstract sockets" that exist only in memory and don't have
a corresponding file in /tmp.
On most other flavors of UNIX, it's possible for the socket files to leak when programs using D-Bus exit abnormally or without closing
their D-Bus connections. Thus, it might be interesting to run dbus-cleanup-sockets in a cron job to mop up any leaked sockets. Or you can
just ignore the leaked sockets, they aren't really hurting anything, other than cluttering the output of "ls /tmp"
AUTHOR
dbus-cleanup-sockets was adapted by Havoc Pennington from linc-cleanup-sockets written by Michael Meeks.
