### XmlRpc++ Library

This is version 0.7 of XmlRpc++, an implementation of the XmlRpc protocol written in C++, based upon Shilad Sen's excellent py-xmlrpc library. XmlRpc++ is designed to make it easy to incorporate XmlRpc client and server support into C++ applications. Or use both client and server objects in your app for easy peer-to-peer support.

### Features

- Easy This library is easy to incorporate into C++ applications. No other libraries are required, other than your system's socket libraries. Simple XML parsing and HTTP support are built in.
- Fast All IO is non-blocking, so a slow client or network will not slow down the server.
- Portable Written in standard C++ to the POSIX and Windows sockets APIs. You do need a fairly recent compiler (g++ 3.1 or MSVC++ .Net or MSVC++ 6 with the STL patches.)
- Free This library is released under the GNU LGPL.

### Changes

- Better handling of fault responses: server methods can throw an XmlRpcException to return a fault and XmlRpcClient has a new method to test whether the last response was a fault.
- Support for system.listMethods and system.methodHelp from the introspection API.
- Support for system.multicall to process multiple requests in a single transaction.
- Fixed a problem in the XmlRpcServer destructor (it should not have been deleting the methods).
- The server ensures a valid result value is returned even if the method does not set the result. The default result is an empty string.
- Doxygen comments in header files and a doc target in the makefile.

### Installation

There are VC++ 6 and VC++ .Net project files building on Windows. If you are using VC++ 6, you should apply SP3 and the fixes at http://www.dinkumware.com/vc_fixes.html. Be sure to set the appropriate code generation switches. In particular, ensure that the runtime library (single/multi-threaded, static library/DLL) used is the same for the XmlRpc++ code and whatever application it will be linked to.

For Linux, Solaris, and other Unix-like platforms there is a GNU Makefile which can be edited to suit your system. Specify your C++ compiler, compiler flags, and your system's socket libraries.

In the test directory there are various test programs that are built by default. To verify that the library built correctly, you can start the HelloServer example:

    HelloServer 8000

and the HelloClient example in another terminal window:

    HelloClient localhost 8000

You should see two Hello messages and a sum displayed (amongst a bunch of debug output). You can also try the XML server validator program (eg, "Validator 80") and then attempt to connect to it from http://validator.xmlrpc.com (if you have access to the internet and are not behind a firewall etc).

Although no code was re-used, the design and structure of the library is based upon the py-xmlrpc library implementation.
