Hmm, was wondering about that. Initially I did not have the declaration, but then I got an error about 'my_perl' undeclared. I found some code online (that I didn't read thoroughly, I see) and declared the variable.
Apparently, that is not enough. Any good examples/tutorials on how to do this?
Or perhaps I'm taking the wrong approach here and there is a better way. Here's what I'm trying to do. I'm trying to write a function in C that can be called from perl that takes as input, basically argc and argv. It seems you can't actually pass an array of char * from perl, you need to handle an AV *. I'd like to keep all this code in the external library, instead of writing it in the XS file, but maybe I'm just making it harder for myself that way.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

are good places to start.
