There are two main ways: XS and Inline::C. I'm a big fan of xs, but I believe the inline C is considered easier to learn. You'll almost certainly have to write some kind of wrapper to pull the functions up into your application — unless someone has already done the ground work. UPDATE: correction... three main ways. I was unaware of this Win32::API namespace. That makes everything a lot simpler I bet. I now wonder if there's such a thing for elf.so. -Paul	[reply]

Take a look at Win32::API & Win32::API::Prototype. If you are using an Active State build you probably have the former already installed. I find the latter easier to use, but installing it isn't trivial. If you encounter problems, come back with what you have, and the function signatures of the APIs you are trying to access and you'll get more help. Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice. "Too many [] have been sedated by an oppressive environment of political correctness and risk aversion."	[reply]

There is an example of how to do this (using an XSUB) from quite a while ago: callbacks in XS code.	[reply]
