There isn't one single way, and unfortunately there isn't an exact guide that shows how to write any possible bindings. You can use the following guides: * http://perldoc.perl.org/perlxs.html * http://www.lemoda.net/xs/index.html * https://github.com/xsawyerx/xs-fun/ You will need to think of the interface. For example, the questions: * How will the API look like? * Should I use objects? * Do I use "magic" to store the details? * etc. Otherwise, great stuff. Good luck! :)
