Exactly what is it that you don't understand?

Did you read the docs for Inline::C? Did you review the examples?

Are you having trouble with data passing? Linking? Data types? Turning on your computer?

Did you read the Inline C cookbook?

Did you use Super Search to find helpful nodes, like Getting Started with Inline::C?

Do a little research on your own. (You might have, but from your question I really couldn't tell.) Then, give something a try. If you have an error, then ask a more specific question. Your question is vague enough that it's too much work to try to answer it. Make it easy on us!
