bsl::basic_string<wchar_t>::rfind

Return the starting position of the last occurrence of a substring whose value equals that of the specified characterString of the optionally specified numChars length, if such a substring can be found in this string (on or before the optionally specified position if such a position is specified), and return npos otherwise. If numChars is not specified, CHAR_TRAITS::length(characterString) is used.
