This is a Perl interface to the client facilities of XML-RPC for C/C++ (aka Xmlrpc-c). XML-RPC is a quick-and-easy way to make procedure calls over the Internet. It converts the procedure call into XML document, sends it to a remote server using HTTP, and gets back the response as XML. See . Also see RPC::XML. That serves the same purpose, but is is Perl all the way down to the operating system. Its modules call other Perl modules that provide HTTP and XML services, and those call other Perl modules, etc. By contrast, RPC::Xmlrpc_c::Client calls executable (machine language) libraries which are part of XML-RPC For C/C++. It requires much less CPU time. See below for details. Prerequisite: XML-RPC For C/C++. You must have this installed on your system before building the RPC-Xmlrpc_c package. You must have a working 'xmlrpc-c-config' shell command too; otherwise, you'll have to modify the Makefile.PL's to tell them how to link C code with your XML-RPC For C/C++ installation. You need Release 1.09 (December 2006) or better of XML-RPC For C/C++. XML-RPC For C/C++ probably will not work out-of-the-box on anything but Unix. See . Written by Bryan Henderson, December 2006.

PERFORMANCE ----------- Compared to the RPC-XML package (RPC::XML::Client, etc): In an experiment with a simple "add two integers" RPC in December 2006, a Perl program (which does nothing else) took 3 times as much CPU time to start up, perform one RPC, and report the result with RPC::XML::Client as with RPC::Xmlrpc_c::Client. Subsequent RPCs (with the same client object, but everything else repeated) took 10 times as much CPU time with RPC::XML:Client as with RPC::Xmlrpc_c::Client.
