Version 0.1 released
libdaemon is a lightweight C library that eases the writing of UNIX daemons. It consists of the following parts:
APIs like these are used in most daemon software available. It is not that simple to get it done right and code duplication is not a goal.
libdaemon is currently used by ifplugd, Avahi, ivam2, Nautilus-Share and aeswepd.
Version 0.13 is feature complete.
An extensive API reference is available
libdaemon was developed and tested on Debian GNU/Linux "testing" from July 2003, it should work on most other Linux distributions (and some Unix versions) since it uses GNU Autoconf and GNU libtool for source code configuration and shared library management.
libdaemon is known to work on modern Linux systems, FreeBSD, NetBSD, OpenBSD, Darwin, Solaris and Windows/Cygwin.
As this package is made with the GNU autotools you should run ./configure inside the distribution directory for configuring the source tree. After that you should run make for compilation and make install (as root) for installation of libdaemon.
Please use gmake instead of traditional make for compilation on non-Linux systems.
Sebastien Estienne, for a lot of portability work.
