Assure que l'espace à la zone de mise au moins un caractère en enregistrant une certaine séquence initiale de caractères commençant au
pbase() à la séquence de sortie et mise à jour des pointeurs de la zone de sortie (si nécessaire). Si ch n'est pas traits::eof() (c.-à-traits::eq_int_type(c, traits::eof()) != true), il est soit mise à la zone de sortie ou directement enregistrées dans la séquence de sortie .Original:
Ensures that there space at the put area for at least one character by saving some initial subsequence of characters starting at
pbase() to the output sequence and updating the pointers to the output area (if needed). If ch is not traits::eof() (i.e. traits::eq_int_type(c, traits::eof()) != true), it is either put to the output area or directly saved to the output sequence.The text has been machine-translated via Google Translate.
