Do nothing — wk_void • wk

This handler does nothing and returns NULL. It is useful for benchmarking readers and handlers and when using filters that have side-effects (e.g., wk_debug()). Note that this handler stops on the first parse error; to see a list of parse errors see the wk_problems() handler.
