Windows AP にコンソール出力を提供するクラス
表題の通りです。コメントもありません。DEBUGCONSOLEが定義されている場合のみコンソールが作成されます。
CDebugConsole クラスのメンバを以下に示します。
- GetInstance
- 唯一のインスタンスへの参照を返します
- SetConsoleTitle
- コンソールのタイトルバー文字列を更新します
- Printf
- 標準出力に書式付きで出力します
- Errorf
- 標準エラー出力に書式付きで出力します
- VPrintf
- 引数リストへのポインタを使用して、標準出力に書式付きで出力します
- VErrorf
- 引数リストへのポインタを使用して、標準エラー出力に書式付きで出力します
- Dump
- 渡されたデータを16進でダンプした結果を標準出力に出力します
CDebugConsole クラスのインスタンスは1個のみの存在とし、CDebugConsole::GetInstance () で参照を取得します。
int n = 10;
CDebugConsole::GetInstance ().Printf ("n は %d です。", n);
また、C ソースにインクルードした場合に同等の機能を提供する関数も定義しています。
