strnlen_s is in Annex K, which is an optional part of the standard. Incidentally, no libc in widespread usage has implemented it.

True. The non standard strnlen is however more widespread. Microsoft implements strnlen_s in terms of strnlen like so.

    _String == 0 ? 0 : strnlen(_String, _MaxCount)
