Se una zona di messa esiste (ad esempio, il file è stato aperto per la scrittura), le chiamate overflow() di scrivere tutto l'output in attesa del file.

Se un'area get esiste (ad esempio, il file è stato aperto per la lettura), l'effetto è definito dall'implementazione. Tipica applicazione può svuotare l'area get e spostare la posizione corrente nel file indietro di un corrispondente numero di byte.
Original:
If a get area exists (e.g. the file was opened for reading), the effect is implementation-defined. Typical implementation may empty out the get area and move the current file position back by the corresponding number of bytes.
