The difference between doing XS in C and in C++ isn't all that rough.
See "Using XS With C++" in perlxs.pod. The Perl API however is C so it
feels more natural doing it in C (but since I in general find C more
natural than C++, I am slightly biased on that).

Foremost it was fun which helped a lot over all the complexities and
subtleties of XS. The hardest part is probably grokking the
idiosyncratic XS documentation that lacks some vital things (typemaps,
for instance, are explained nowehere).
You get some useful examples in the two XS-cookbooks that you find at
http://search.cpan.org/author/DMR/
They don't contain a lot of descriptive explanations (I think they even
contain none at all) but still they are a great help.
Other than that, perlxstut, perlguts, perlxs and perlapi will be the
manpages you need. Roughly in this order save for perlapi.pod which is
the reference for all the API functions and macros.
