Defined in header <cwchar>
wchar_t* wmemset( wchar_t* dest, wchar_t ch, std::size_t count );
chが指すオブジェクトの最初のcountワイド文字のそれぞれにコピーし、ワイド文字dest。オブジェクト(例えば、スカラー、配列、またはC互換の構造体)-自明コピー可能でない場合、動作は未定義です。オブジェクトの外側dest+size+1指している場合、動作は未定義です.
Original:
Copies wide character ch into each of the first count wide characters of the object pointed to by dest. If the object is not trivially-copyable (e.g., scalar, array, or a C-compatible struct), the behavior is undefined. If dest+size+1 points outside the object, the behavior is undefined.
