<h4 class="subsection">7.4.5 Using the example options</h4>

<p>Normally, however, you would not use the <code>main</code> clause.  Instead,
the file would be named something like <samp>checkopt.def</samp>, you would
compile <samp>checkopt.c</samp> the usual way, and link the object with the rest
of your program.
</p>
<p>The options are processed by calling <code>optionProcess</code>
(see <a href="libopts_002doptionProcess.html#libopts_002doptionProcess">libopts-optionProcess</a>):
</p>
<div class="example">
<pre class="example">main( int argc, char** argv )
{
  {
    int optct = optionProcess( &amp;checkOptions, argc, argv );
    argc -= optct;
    argv += optct;
  }
</pre></div>

<p>The options are tested and used as in the following fragment.
<code>ENABLED_OPT</code> is used instead of <code>HAVE_OPT</code> for the
<samp>--show-defs</samp> option because it is an enabled/disabled option type:
</p>
<div class="example">
<pre class="example">  if (  ENABLED_OPT( SHOW_DEFS )
     &amp;&amp; HAVE_OPT( CHECK_DIRS )) {
    int    dirct = STACKCT_OPT( CHECK_DIRS );
    char** dirs  = STACKLST_OPT( CHECK_DIRS );
    while (dirct-- &gt; 0) {
      char* dir = *dirs++;
      ...
</pre></div>
