<h2>global.c -- global variables and their functions</h2>
<blockquote>
<p>Qhull uses a global data structure, <tt>qh</tt>, to store
globally defined constants, lists, sets, and variables. This
allows multiple instances of Qhull to execute at the same time.
The structure may be statically allocated or
dynamically allocated with malloc(). See
<a href="user.h#QHpointer">QHpointer</a>.
</p>
