Hey perl monks, I just got a book on Exending and Embedding.

Would that be this book?

I just don't understand what perl api is

The perl API (Application Program Interface) is the interface to use when talking to the perl interpreter from C/C++ and possibly other languages.

Would all my C code with my perl code would look like this <perl.h> that if i am right.

There's a little more to it that that - if I'm even understanding what you're asking - if you're asking anything. In other words, you're not making yourself very clear.

If you want to embed a perl interpreter to your (C/C++) programs take a look at "Adding a perl interpreter to your C program" in perlembed.

If you want to add C code to your perl programs take a look at perlxs.

Or, you know, read that book you've got.
