you can use something like this to perform your task (largely based on code from Inline::C-Cookbook)It's a bad example in the Cookbook, and thank you for reminding me that it needs to be fixed. Your code (and the Cookbook example) are fine if run just once - but if you call the Inline::C sub more than once, then things can go screwy.
For example, with the code you posted, if I call it 10 times:
c_func('AAA:BBB');
c_func('AAA:BBB');
c_func('AAA:BBB');
c_func('AAA:BBB');
c_func('AAA:BBB');
c_func('AAA:BBB');
c_func('AAA:BBB');
c_func('AAA:BBB');
c_func('AAA:BBB');
c_func('AAA:BBB');
I get this output:
AAA - BBB
CCC - DDD
CCC - DDD
If I call the sub 10 times in a loop:
for(1 .. 10) {c_func('AAA:BBB')}
I get:
Use of uninitialized value $1 in concatenation (.) or string at try.pl
+ line 10.
Use of uninitialized value $2 in concatenation (.) or string at try.pl
+ line 10.

Use of uninitialized value $2 in concatenation (.) or string at try.pl

AAA - BBB
CCC - DDD
AAA - BBB
CCC - DDD
CCC - DDD
The problem is that the Inline Stack macros are deficient for performing callbacks - and one should instead base one's callbacks on the
perlcall documentation (from where my example was drawn).

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).
