complex-types-client-eina-value.c

Client to test complex types (arrays, structs, dicts) against a provided server (complex-types-server.c) returning them as Eina_Value to/from Message.

//Compile with:
// gcc -o complex-types-client-eina-value complex-types-client-eina-value.c `pkg-config --cflags --libs eldbus ecore eina`
