libxmlrpc-core-c3-dev binary package in Ubuntu Focal i386

 XML-RPC is a quick-and-easy way to make procedure calls over the Internet.
 It converts the procedure call into an XML document, sends it to a remote
 server using HTTP, and gets back the response as XML.

 This library provides a modular implementation of XML-RPC for C.
