readability-named-parameter

Find functions with unnamed arguments.

The check implements the following rule originating in the Google C++ Style Guide:

https://google.github.io/styleguide/cppguide.html#Function_Declarations_and_Definitions

All parameters should have the same name in both the function declaration and definition. If a parameter is not utilized, its name can be commented out in a function definition.

int doingSomething(int a, int b, int c);

int doingSomething(int a, int b, int /*c*/) {
    // Ok: the third param is not used
    return a + b;
}

Corresponding cpplint.py check name: readability/function.
