文字出力シーケンスに
pbase()から始まり、出力領域へのポインタを更新する（必要な場合）のいくつかの初期のサブシーケンスを保存することにより、少なくとも1文字の出力領域であり、そのスペースを確保します。 chされていない場合はtraits::eof()（すなわちtraits::eq_int_type(c, traits::eof()) != true）、それはどちらの出力領域に置くか、または直接出力シーケンスに保存されます.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.

関数は
pptr、epptrとpbackポインタはより多くのデータを書き込むための場所を定義するために更新することがあります。失敗した場合、関数はそのどちらpptr() == nullptrまたはpptr() == epptr確実に.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.The text has been machine-translated via Google Translate.

関数の基本クラスのバージョンは何もしません。派生クラスは、枯渇の場合get領域への更新を許可するには、この関数をオーバーライドすることができます.
Original:
The base class version of the function does nothing. The derived classes may override this function to allow updates to the get area in the case of exhaustion.
