Dear monks, I have a perplexing problem. I need to integrate BarclayCard's ePDQ credit card authentication system (you know, the rather pointless Verified by Visa/Mastercard SecureCode thing) with an existing Perl shopping card I wrote. The Perl isn't the problem. The problem is that Barclaycard, in their wisdom, provide an API in C++ or Java. I don't do either - I do Perl or PHP! However, I thought using XS might be the answer, creating my own Perl library interfacing to the supplied shared object file (which I don't have the source for of course, but do have a header file). I have taken a look at the manpage perlxstus and am now even more confused! Anyone have any ideas where to start? I basically need to make a Perl interface to a shared object where I don't even have the source code (but do have the header file). The header file is 1734 lines long so I can't post it here, but I'm posting a snippet here: 
MS_API_EXTERN 
int xfortInitializePAReqBuffer(unsigned int uPAReqBufLen, 
                               asc7char *pPAReqBuf,
                               XFortCreatePAReqResult *result,
                               asc7char *szErrMsgBuf, 
                               unsigned int uErrMsgBufLen);

Thanks in advance, oh wise ones! Neil p.s. At least the header file is well documented!
