Si
empty() vuelve false, el puntero es tal que el [data(); data() + size()) rango es válida y los valores en que se corresponden con los valores almacenados en la cadena. Si vuelve empty() true, el puntero es un puntero no nulo que no debe dejar de hacer referencia. (hasta C++11)Original:
If
empty() returns false, the pointer is such that the range [data(); data() + size()) is valid and the values in it correspond to the values stored in the string. If empty() returns true, the pointer is a non-null pointer that should not be dereferenced. (hasta C++11)The text has been machine-translated via Google Translate.
