## 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.

#### Example:

    // actions are performed in the functions "setup" and "loop"
    // but  no information is reported to the larger program

    void setup()
    {
      // ...
    }

    void loop()
    {
      // ...
    }
