XML-RPC for C/C++ (Xmlrpc-c) Code

/*============================================================================
  Act like a CGI script -- read POST data from Standard Input, interpret
  it as an XML-RPC call, and write an XML-RPC response to Standard Output.

  This is for use by a test program.
