size_type rfind(E c, size_type pos = npos) const;
size_type rfind(const E *s, size_type pos = npos) const;

Each member function finds the last (highest beginning position) subsequence in the controlled sequence, beginning on or before position pos, that matches the operand sequence specified by the remaining operands. If it succeeds, it returns the position where the matching subsequence begins. Otherwise, the function returns npos.
