std::streamsize in_avail();
get領域で使用可能な文字の数を返します。読み込み位置が利用可能であれば、事実上、egptr() - gptr()get領域のサイズを返します。この場合、返されたバイト数がunderflow()を呼び出すことなく、バッファから抽出することができるバイト数です.
Original:
Returns the number of characters available in the get area. If a read position is available, effectively returns egptr() - gptr(), the size of the get area. In this case, the number of bytes returned is the number of bytes that can be extracted from the buffer without calling underflow().

get領域が空の場合は、showmanyc()は、関連する文字シーケンスで使用可能なバイト数を決定するために呼び出します。この場合、返された値は、それがunderflow()Traits::eofを返さないことを保証されている間にバッファから抽出することができるバイト数です.
Original:
If the get area is empty, calls showmanyc() to determine the number of bytes available in the associated character sequence. In this case, the value returned is the number of bytes that can be extracted from the buffer while it's guaranteed that underflow() would not return Traits::eof.
