# Extra Clang Tools 18.1.8 documentation

## clang-tidy - readability-named-parameter

# 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.
