const CharT* c_str()const;

Gibt einen Zeiger auf eine Null-terminierte Zeichenarray mit Daten entsprechen denen in der Zeichenkette gespeichert. Der Zeiger ist derart, dass der Bereich [c_str(); c_str() + size()] gültig ist und die Werte darin zu den Werten in der Zeichenfolge mit einem zusätzlichen Null-Zeichen nach der letzten Position gelagert entsprechen .

Original:

Returns a pointer to a null-terminated character array with data equivalent to those stored in the string. The pointer is such that the range [c_str(); c_str() + size()] is valid and the values in it correspond to the values stored in the string with an additional null character after the last position.
