It doesn't matter which code embeds what. The only real difference between embedding perl in C and C in perl is that if you embed C code in perl you can use the standard perl interpreter to start everything, and otherwise you'll have to "manually" start the perl interpreter using a (short) bootstrap sequence in C. Once you've done that, you can call into C and C++ functions from perl and vice versa regardless of how the startup procedure was executed.

You do it the same way as calling functions from a shared library: you wrap the functions - using XS - yourself. "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply]

You can look at the code produced by Inline::CPP to see how it calls CPP routines and how it compiles and links the code. In short, it is a way for you to generate your own examples that call your own code. But I agree that it will not produce an example of a C++ routine calling an embeded perl interpreter calling a C++ routine - sorry...	[reply]
