/* A simple standalone XML-RPC server based on Abyss that processes a
|
|
single RPC from an existing TCP connection on Standard Input.
|
|
|
|
A typical example of where this would be useful is with an Inetd
|
|
"super server."
|
|
|
|
xmlrpc_sample_add_server.c is a server that does the same thing,
|
|
but you give it a TCP port number and it listens for TCP connecitons
|
|
and processes RPCs ad infinitum. xmlrpc_socket_server.c is halfway
|
|
in between those -- you give it an already bound and listening
|
|
socket, and it lists for TCP connections and processes RPCs ad
|
|
infinitum.
|
|
|
|
Here is an easy way to test this program:
|
|
|
|
socketexec --accept --local_port=8080 --stdin -- ./xmlrpc_inetd_server
|
|
|
|
Now run the client program 'xmlrpc_sample_add_client'. Socketexec
|
|
will accept the connection that the client program requests and pass it
|
|
to this program on Standard Input. This program will perform the RPC,
|
|
respond to the client, then exit.
