parentecore_con_client_example: allow more features and protocols to be used. (diff)
downloadefl-2d2dc4de4b63a4fef5c38786211443ccc5e9157d.tar.gz
ecore_con_server_example: allow more features and protocols to be used.
Instead of a single SSL connection, allow for local, tcp and udp, optional flush and delete-after-write (--single-message) and echo mode. Very similar to ecore_ipc_server_example.c
