<p>I need to use XmlRpc in C++ on a Windows platform.  Despite the fact that my friends assure me that XmlRpc is a "widely available standard technology", there are not many libraries available for it.  In fact I only found one library to do this on Windows, (plus another one that claims "you'll have to do a lot of work to get this to compile on Windows).  The library I found was Chris Morley's "XmlRpc++".  However, it doesn't have support for SSL.</p>

<p>My question therefore is:  what library should I be using?  </p>

There are dozens of implementations of the XML-RPC
implementations
, some in C++, but most in other languages. For example, besides XmlRpc++ there is also
XML-RPC for C and C++
. Here is a
HOWTO
on how the XML-RPC for C and C++ library can be used.
The XML-RPC specification is somewhat simple and it would not be difficult to implement your own XML-RPC client. Not to mention, it would also be possible to take an existing XML-RPC implementation in C and bring into your C++ project.
The XML-RPC
home page
also provides a lot of useful information.
