Shared memory for shared library

I am writing a shared library in Linux (but compatible with other UNIXes) and I want to allow multiple instances to share a piece of memory -- 1 byte is enough. What's the "best" way to do this? I want to optimize for speed and portability. Obviously, I'll have to worry about mutual exclusion.

uuidd

UUIDD(8)						       System Administration							  UUIDD(8)

NAME

       uuidd - UUID generation daemon

SYNOPSIS

       uuidd [options]

DESCRIPTION

       The  uuidd  daemon is used by the UUID library to generate universally unique identifiers (UUIDs), especially time-based UUIDs, in a secure
       and guaranteed-unique fashion, even in the face of large numbers of threads running on different CPUs trying to grab UUIDs.

OPTIONS

       -d, --debug
	      Run uuidd in debugging mode.  This prevents uuidd from running as a daemon.

       -F, --no-fork
	      Do not daemonize using a double-fork.

       -k, --kill
	      If currently a uuidd daemon is running, kill it.

       -n, --uuids number
	      When issuing a test request to a running uuidd, request a bulk response of number UUIDs.

       -P, --no-pid
	      Do not create a pid file.

       -p, --pid path
	      Specify the pathname where the pid file should be written.  By default, the pid file is written to /run/uuidd/uuidd.pid.

       -q, --quiet
	      Suppress some failure messages.

       -r, --random
	      Test uuidd by trying to connect to a running uuidd daemon and request it to return a random-based UUID.

       -S, --socket-activation
	      Do not create a socket but instead expect it to be provided by the calling process.  This  implies  --no-fork  and  --no-pid.   This
	      option is intended to be used only with systemd(1).  It needs to be enabled with a configure option.

       -s, --socket path
	      Make  uuidd use this pathname for the unix-domain socket.  By default, the pathname used is /run/uuidd/request.  This option is pri-
	      marily for debugging purposes, since the pathname is hard-coded in the libuuid library.

       -T, --timeout number
	      Make uuidd exit after number seconds of inactivity.

       -t, --time
	      Test uuidd by trying to connect to a running uuidd daemon and request it to return a time-based UUID.

       -V, --version
	      Output version information and exit.

       -h, --help
	      Display help screen and exit.

EXAMPLE

       Start up a daemon, print 42 random keys, and then stop the daemon:

	      uuidd -p /tmp/uuidd.pid -s /tmp/uuidd.socket
	      uuidd -d -r -n 42 -s /tmp/uuidd.socket
	      uuidd -d -k -s /tmp/uuidd.socket

AUTHOR

       The uuidd daemon was written by Theodore Ts'o <tytso@mit.edu>.

SEE ALSO

       uuid(3), uuidgen(1)

AVAILABILITY

       The uuidd daemon is part of the util-linux package and is available from the Linux Kernel  Archive  <https://www.kernel.org/pub/linux/utils
       /util-linux/>.
