Glib::Module

[Bart Verstraete <bartverstraete telenet be>]

Hi here follows the samplecode and the question is. I get no errors, it 
seems to load the moduleeee only when I try to acces the function via 
get_symbol() the sample app print this:
Name of the plugin: plugins/sample.dll
Error: `action': The specified procedure could not be found.

Sourcecode:

////The App////

//main.cpp
#include <iostream>
#include <glibmm/module.h>
#include "TestPluginApp_generic.h"
int main()
{
   void *actionpl = 0;
   Glib::Module plugin("plugins/sample.dll");
   if(!plugin)
       std::cout << "Error: " << plugin.get_last_error() << std::endl;
   else
   {
       std::cout << "Name of the plugin: " << plugin.get_name() << 
std::endl;
       if(plugin.get_symbol("action", actionpl))
           std::cout << "Function exist" << std::endl;
       else
           std::cout << "Error: " << plugin.get_last_error() << std::endl;
   }
   return 0;
