Change the length of this string to the specified newLength, erasing characters at the end if newLength < length() or appending the appropriate number of characters at the end if length() < newLength. Subsequently, invoke the specified operation passing the address of the null‐terminated buffer and the adjusted length of this string as parameters. Finally, change the length of this string to the value returned by the operation. Throw length_error if newLength > max_size(). The behavior is undefined unless the value returned by the operation is less than or equal to newLength.
