.. _arduino-void:
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()
{
// ...
}
