94<h2><a name="overview">Overview</a></h2>
95
96<p><tt>libdaemon</tt> is a lightweight C library that eases the writing of UNIX
97daemons. It consists of the following parts:</p>
98
99<ul>
100 <li>A wrapper around <tt>fork()</tt> which does the correct
101 daemonization procedure of a process</li>
102
103 <li>A wrapper around <tt>syslog()</tt> for simpler and compatible
104 log output to Syslog or STDERR</li>
105
106 <li>An API for writing PID files</li>
107
108 <li>An API for serializing UNIX signals into a pipe for
109 usage with <tt>select()</tt> or <tt>poll()</tt></li>
110
111 <li>An API for running subprocesses with STDOUT and STDERR redirected to syslog.</li>
112</ul>
113
114<p>APIs like these are used in most daemon software
115available. It is not that simple to get it done right and code
116duplication is not a goal.</p>
117
118<p><tt>libdaemon</tt> is currently used by <a

130<p>Version @PACKAGE_VERSION@ is feature complete.</p>

136
137<h2><a name="requirements">Requirements</a></h2>
138
139<p><tt>libdaemon</tt> was developed and tested on Debian GNU/Linux
140"testing" from July 2003, it should work on most other Linux
141distributions (and some Unix versions) since it uses GNU Autoconf and
142GNU libtool for source code configuration and shared library
143management.</p>
144
145<p><tt>libdaemon</tt> is known to work on modern Linux systems, FreeBSD, NetBSD, OpenBSD, Darwin, Solaris and Windows/Cygwin.</p>
146
147<h2><a name="installation">Installation</a></h2>
148
149<p>As this package is made with the GNU autotools you should run
150<tt>/configure</tt> inside the distribution directory for configuring
151the source tree. After that you should run <tt>make</tt> for
152compilation and <tt>make install</tt> (as root) for installation of
153<tt>libdaemon</tt>.</p>
154
155<p>Please use <tt>gmake</tt> instead of traditional <tt>make</tt> for compilation on non-Linux systems.</p>
