BOOL FindNextPrinterChangeNotification( HANDLE hChange, PDWORD ChangeFlags, LPPRINTER_NOTIFY_OPTIONS PrinterNotifyOptions, LPPRINTER_NOTIFY_INFO *PrinterNotifyInfo);
この関数の詳しい説明については、SDKのドキュメントか、後述に記したサンプルを参照。
引数の意味は、以下の通り。
| hChange | 変更通知オブジェクトのハンドル。 |
| ChangeFlags | どのようなイベントが起こったのかを表すフラグ。PRINTER_CHANGE_XXXの組み合わせ。 |
| PrinterNotifyOptions | 次回変更情報取得時にどのような情報を受け取るかを指定するデータ。フラグにPRINTER_NOTIFY_OPTIONS_REFRSHを指定した場合、すべての情報を受け取る。(JOB型は返らない) |
| PrinterNotifyInfo | 変更通知情報を格納位置を受け取るためのポインタのポインタ。 |
