What is the explanation of the code?

Question

Could anybody tell me what is the following code? Is it function declaration or statement? Is it valid code?

    { status_screens, settings_screens, access_screens, configuration_screens,
      history_screens };

Answer 1

its a constant array of function pointers that of signature void foo(void)

Those are the easy ones. Google C Complex Declaration for the exciting ones.
