Session
=======

The zenoh session is created using the :cpp:func:`zenoh::Session::open` function, 
consuming the configuration object :cpp:class:`zenoh::Config`.
Then a string is published on "demo/example/simple" key expression.

.. code-block:: c++

   #include "zenoh.hxx"
   using namespace zenoh;

   int main(int argc, char **argv) {
      try {
         Config config = Config::create_default();
         auto session = Session::open(std::move(config));
         session.put(KeyExpr("demo/example/simple"), "Simple!");
      } catch (ZException e) {
         std::cout << "Received an error :" << e.what() << "\n";
      }
   }
