/*=============================================================================
sample_add_client_complex.cpp
===============================================================================
This is an example of an XML-RPC client that uses XML-RPC for C/C++
(Xmlrpc-c).
In particular, it uses the complex lower-level interface that gives you
lots of flexibility but requires lots of code. Also see
xmlrpc_sample_add_server, which does the same thing as this program,
but with much simpler code because it uses a simpler facility of
Xmlrpc-c.
This program actually gains nothing from using the more difficult
facility. It is for demonstration purposes.
