const CharT* c_str() const;

Renvoie un pointeur sur un tableau de caractères terminée par NULL avec des données équivalentes à celles stockées dans la chaîne. Le pointeur est telle que la plage de [c_str(); c_str() + size()] est valide et les valeurs qui y correspondent aux valeurs stockées dans la chaîne de caractères avec un caractère nul en sus de la dernière position .

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.

Le pointeur obtenu à partir c_str() ne peut être traité comme un pointeur vers une chaîne de caractères terminée par NULL si l'objet chaîne ne contient pas d'autres caractères nuls .

Original:

The pointer obtained from c_str() may only be treated as a pointer to a null-terminated character string if the string object does not contain other null characters.
