misc-unused-parameters
Finds unused function parameters. Unused parameters may signify a bug in the code (e.g. when a different parameter is used instead). The suggested fixes either comment parameter name out or remove the parameter completely, if all callers of the function are in the same translation unit and can be updated.
The check is similar to the -Wunused-parameter compiler diagnostic and can be used to prepare a codebase to enabling of that diagnostic. By default the check is more permissive (see :option:`StrictMode`).
