<h1 style="margin-top:0px">hgeCreate function</h1>
<p>
Creates the <b>HGE</b> object if needed and returns a pointer to the <b>HGE</b> interface.
</p>
<pre>
HGE *hgeCreate(
int <i><b>ver</b></i>
);
</pre>
<h2>Parameters</h2>
<dl>
<dt><i>ver</i>
<dd><b>HGE</b> API version number. Just pass the <b>HGE_VERSION</b> constant here.
</dl>
<h2>Return value</h2>
<p>
If the loaded HGE.DLL contains compatible API, <b>hgeCreate</b> returns a pointer to the <b>HGE</b> interface. Otherwise it returns 0.
</p>
<h2>Remarks</h2>
<p>
<b>hgeCreate</b> is a global C function. It is located outside of any classes and is imported from the <b>HGE</b> DLL.
<br><br>
To access <b>HGE</b> functions you need the HGE interface pointer that is returned by <b>hgeCreate</b> function.
<b>hgeCreate</b> creates a <b>HGE</b> object if needed and increases the internal reference counter.
To free obtained interface you must call the <a href="hgefunc_interfacerelease.html">Release</a>
function.
<br><br>
You may call <b>hgeCreate</b> every time you need access to <b>HGE</b>,
then call <a href="hgefunc_interfacerelease.html">Release</a>. Or you may get the
interface once during startup and store it in a global variable, then release during cleanup.
Although the latter is supposed to be 'bad style', this works fine with not very big projects
and all <b>HGE</b> helper classes use this approach.
</p>
<h2>Requirements</h2>

<b>Header:</b> hge.h<br>
<b>Import library:</b> hge.lib
