What is daemon?

Daemon turns other process into daemons. There are many tasks that need to be performed to correctly set up a daemon process. This can be tedious. Daemon performs these tasks for other processes. This is useful for writing daemons in languages other than C, C++ or Perl (e.g. /bin/sh, Java).

If you want to write daemons in languages that can link against C functions (e.g. C, C++), see libslack which contains the core functionality of daemon.

Daemon is freely available under the GNU General Public License.

Features

Sets up the correct process context for a daemon.
Behaves sensibly when started by initd(8) or inetd(8).
Revokes any setuid or setgid privileges to reduce security risks in case daemon is incorrectly installed with special privileges.
Prevents the generation of core files to prevent leaking sensitive information from daemons run as root (optional).
Names the daemon by creating and locking a PID file to guarantee that only one daemon with the given name can execute at any given time (optional).
Sets the user and group under which to run the daemon (optional, root only).
Creates a chroot gaol (optional, root only).
Captures the daemon's stdout and stderr and directs them to syslog (optional).
Respawns the daemon when it terminates (optional).
Automatically terminates the daemon when the user logs out (optional, only on systems with systemd-logind(8) or elogind(8)).
Configuration files to define default options for different daemons (optional).

For more information read the Documentation.

Supported Platforms

Currently, daemon is only known to compile and work on:

Linux 3.x/4.x/... (i386, x86_64, debian-{7,8,9,10,...}, ubuntu-{14.04,16.04}, ...
Linux 2.6 (i386, x86_64, debian-5.0.4, ubuntu-10.04, fedora-13)
Solaris 10 10/09 (i386, amd64), 11 (amd64)
OpenSolaris 2009/06 (i386, amd64)
OpenBSD 4.7 (i386, amd64), 6.6 (amd64)
FreeBSD 8.0 (i386, amd64), 12.1 (amd64)
NetBSD 5.0.2 (i386, amd64), 8.1 (amd64)
MacOSX/macOS 10.{4,5,6,11,14,15}, 11 (ppc, i386, x86_64, arm64)
kFreeBSD 20090729 (i386)
GNU/Hurd (i386)

It is written in ISO C using POSIX almost exclusively except for some BSD functions that appear on most systems (e.g. sockets). So it shouldn't be difficult to get it working on other (recent) systems that support ISO C, POSIX and XPG4.
