+
+``void``
+========
+
+The ``void`` keyword is used only in function declarations. It
+indicates that the function is expected to return no information to
+the function from which it was called, or that it expects no arguments
+from its caller.
+
+Example
+-------
+
+::
+
+    // actions are performed in the functions "setup" and "loop"
+    // but  no information is reported to the larger program
+
+    void setup() {
+      // ...
+    }
+
+    void loop() {
+      // ...
+    }
