No, that’s not correct. For a type that’s meant to be “opaque” (i.e. “users of the interface should not have to know or care about any of the implementation details, historical leakage be damned”), the typedef gives you true opacity… if you’re using “struct kmutex *” rather than “kmutex_t *” then you’re already eating the forbidden fruit. -- thorpej
