Se empty() false retornos, o ponteiro é tal que o intervalo é válido [data(); data() + size()) e os valores em que correspondem aos valores armazenados na cadeia. Se empty() retornos true, o ponteiro é um ponteiro não-nula de que não deve ser dereferenced. (até 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. (até C + 11)
