These is an even better solution, cause it lets me drop one decorator, I have been using at the moment, to handle these things. Thanks a lot. ctypes is so much fun to use. Lately I had to use JNI, and well, compared to this experience I am now in heaven. :) Sadly, I can't provide my team members an equal solution in the Java world, cause one of them starts to hate me for assigning him on another JNI job in our project.
