&gt; <i>get this back</i><p>That never existed. Syntactically it could work; you would need semicolons in there:<p><pre><code>  int func(long_type_name a, b, c; int d);
</code></pre>
similar to struct&#x2F;enum member declarations.<p>Speaking of which: don&#x27;t have long type names in C programs, and simplify API&#x27;s with structs rather than large numbers of parameters. :)
