<h2 class="chapter">1 Introduction</h2>

<p><acronym>CFFI</acronym>, the Common Foreign Function Interface, purports to be
a portable foreign function interface for Common Lisp.

   <p>This specification defines a set of low-level primitives that must be
defined for each Lisp implementation supported by <acronym>CFFI</acronym>. 
These operators are defined in the <code>CFFI-SYS</code> package.

   <p>The <code>CFFI</code> package uses the <code>CFFI-SYS</code> interface
to implement an extensible foreign type system with support for
typedefs, structures, and unions, a declarative interface for
defining foreign function calls, and automatic conversion of
foreign function arguments to/from Lisp types.

   <p>Please note the following conventions that apply to everything in
<code>CFFI-SYS</code>:

     <ul>
<li>Functions in <code>CFFI-SYS</code> that are low-level versions of functions
exported from the <code>CFFI</code> package begin with a leading
percent-sign (eg. <code>%mem-ref</code>).

     <li>Where &ldquo;foreign type&rdquo; is mentioned as the kind of an argument, the
meaning is restricted to that subset of all foreign types defined in
<a href="#Built_002dIn-Foreign-Types">Built-In Foreign Types</a>.  Support for higher-level types is
always defined in terms of those lower-level types in <code>CFFI</code>
proper. 
</ul>

<blockquote><p>Load the foreign shared library <var>name</var>.

        <p><em>Implementor's note: There is a lot of behavior to decide here.  Currently I lean
toward not requiring NAME to be a full path to the library so
we can search the system library directories (maybe even get
LD_LIBRARY_PATH from the environment) as necessary.</em>
