<a href = "References#Blume01">ML-NLFFI</a> is the no-longer-foreign-function interface library for SML. <p>
As of 20050212, MLton has an initial port of ML-NLFFI from SML/NJ to MLton. All of the ML-NLFFI functionality is present.
</p>
<p>
Additionally, MLton has an initial port of the <a href="MLNLFFIGen">mlnlffigen</a> tool from SML/NJ to MLton. Due to low-level details, the code generated by SML/NJ's <tt>ml-nlffigen</tt> is not compatible with MLton, and vice-versa. However, the generated code has the same interface, so portable client code can be written. MLton's <tt>mlnlffigen</tt> does not currently support C functions with <tt>struct</tt> or <tt>union</tt> arguments.
</p>
<h2 id="head-0bb18642b70b9f8a9c12ccf39487328f306b8e19">Usage</h2>
<ul>
<li>
<p>
You can import the ML-NLFFI Library into an MLB file with
<div>
<table>
<tr>
<td align="center">
MLB file</td>
<td align="center">
Description</td>
</tr>
<tr>
<td>
<tt>$(SML_LIB)/mlnlffi-lib/mlnlffi-lib.mlb</tt></td>
<td>
</td>
</tr>
</p>
</table>
</div>
</li>
<li class="gap">
<p>
If you are porting a project from SML/NJ's <a href="CompilationManager">CompilationManager</a> to MLton's <a href="MLBasis"> ML Basis system</a> using <tt>cm2mlb</tt>, note that the following maps are included by default:
<pre>$c/c.mlb $(SML_LIB)/mlnlffi-lib/mlnlffi-lib.mlb
</pre> This will automatically convert a <tt>$/c.cm</tt> import in an input <tt>.cm</tt> file into a <tt>$(SML_LIB)/mlnlffi-lib/mlnlffi-lib.mlb</tt> import in the output <tt>.mlb</tt> file.
</p>
</li>
</ul>
