ecore_con_client_simple_example.c

Shows how to setup a simple client that connects to a server and sends a "hello" string to it. See the complete example description at Ecore_Con - Creating a client

//Compile with:
// gcc -o ecore_con_client_simple_example ecore_con_client_simple_example.c `pkg-config --libs --cflags ecore ecore-con eina`
