const CharT* c_str() const;

Devuelve un puntero a una matriz de caracteres terminada en nulo con los datos equivalentes a los que están almacenados en la cadena. El puntero es tal que el [c_str(); c_str() + size()] rango es válida y los valores que corresponden a los valores almacenados en la cadena con un carácter nulo adicional después de la última posición .

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.
