説明
Buffer からストリームへ、最大 Count バイトを書き込むためのメソッド群です。
WriteData は、ストリームへ書き込むバイト数が固定であるとは限らない場合に使用します。
WriteData が動作するアルゴリズムは以下のとおりです。
- WriteData に
Countパラメータがない場合、WriteData はSizeOf(Buffer)バイトの書き込みを試みます。WriteData は、ストリーム内の現在位置を、転送したバイト数だけ先に進めます。WriteData は書き込んだバイト数を返します。 - WriteData に
Countパラメータがある場合、
WriteData メソッドでは、Write を呼び出して実際の書き込みを行います。
