<!-- AKA "Alien Types" in the CMU CL manual -->
<p>Alien types have a description language based on nested list
structure. For example the C type
<pre class="example"> struct foo {
int a;
struct foo *b[100];
};
</pre>
<p>has the corresponding SBCL <acronym>FFI</acronym> type
<pre class="lisp"> (struct foo
(a int)
(b (array (* (struct foo)) 100)))
</pre>
