int_type overflow( int_type ch = traits::eof() );
Sichergestellt, dass es im Raum gelegt Bereich für wenigstens ein Zeichen durch Speichern einige anfängliche Teilfolge von Zeichen ab pbase() der Ausgangsfolge und der Aktualisierung der Zeiger in den Ausgangsbereich (falls erforderlich). Wenn ch nicht traits::eof() (dh traits::eq_int_type(c, traits::eof()) != true), wird es entweder mit dem Ausgang Bereich gebracht oder direkt mit dem Ausgang Sequenz gespeichert .
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.

Original:
The function may update pptr, epptr and pback pointers to define the location to write more data. On failure, the function ensures that either pptr() == nullptr or pptr() == epptr.
