<H2>DESCRIPTION</H2>
The
<B><A HREF="wiki/Manual for lc_process">lc_process</A></B>(3)
function begins processing of the command line arguments, environment variables, and command line options.
The
<I>argc</I>
and
<I>argv</I>
parameters should be in the same format as passed to the
<B>main</B>
function of your program.
The
<I>appname</I>
parameter should be a reasonable form of the name of the application.
The
<I>type</I>
parameter should describe the format of the configuration file (see below).
The
<I>extra</I>
parameter should list any extra configuration files to process.
<P>
Valid type parameter values:
<DL COMPACT>
<DT>LC_CONF_SECTION<DD>
This type of configuration file is similar to the Windows INI-file style.
An example configuration file:
<PRE>
        &#91;section&#93;
        variable = value
</PRE>
<P>
<DT>LC_CONF_APACHE<DD>
This type of configuration file is similar to the Apache configuration file.
An example configuration file:
<PRE>
        &lt;Section argument&gt;
                variable value
        &lt;/Section&gt;
</PRE>
<P>
<DT>LC_CONF_SPACE<DD>
This is a simple, flat configuration file.  It has no section headers.
An example configuration file:
<PRE>
        variable value
</PRE>
