The variadic function accepts <code class="computeroutput"><span class="number">0</span></code>
to <code class="computeroutput"><span class="identifier">FUSION_MAX_MAP_SIZE</span></code>
elements, where <code class="computeroutput"><span class="identifier">FUSION_MAX_MAP_SIZE</span></code>
is a user definable predefined maximum that defaults to <code class="computeroutput"><span class="number">10</span></code>. You may define the preprocessor constant
<code class="computeroutput"><span class="identifier">FUSION_MAX_MAP_SIZE</span></code> before
including any Fusion header to change the default. Example:
</p>
<pre class="programlisting"><span class="preprocessor">#define</span> <span class="identifier">FUSION_MAX_MAP_SIZE</span> <span class="number">20</span>
