<p>Deleting a global variable from a module is similar to deleting an
instruction. First, you must have a pointer to the global variable that you wish
to delete. Second, you must have a pointer to the module the global variable
belongs to. You use the pointer to the module to get its list of global
variables and then use the erase function to remove your global variable.
<p>Deleting a global variable from a module is just as easy as deleting an
Instruction. First, you must have a pointer to the global variable that you wish
to delete. You use this pointer to erase it from its parent, the module.
For example:</p>
<div class="doc_code">
<pre>
<a href="#GlobalVariable">GlobalVariable</a> *GV = .. ;
<a href="#Module">Module</a> *M = GV-&gt;getParent();
M-&gt;getGlobaleList().erase(GV);
GV-&gt;eraseFromParent();
</pre>
</div>
