.. _lang-void:
``void``
========
.. cpp:type:: void
The ``void`` keyword is used 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() {
// ...
}
