Thanks Rob, I usually use Inine::C to call some C functions from a library or create a skeleton of XS module, it's very handy, and I haven't touched h2xs for long time also. But as you said, example 4 is aim to access to functions in source, in this scenario, Inline C is not very suitable I think, although what h2xs shows in example 4 in perlxstut is not good either.

So what's the good way to generate XS (automatically) for access to a large source distribution? I'll look up ExtUtils::XSpp, hope it's a right way to go.
