Win32API プリンタの構成要素を列挙する EnumPrinterData
プリンタの構成要素を列挙するためには、EnumePrinterData関数を用いる。
DWORD EnumPrinterData(
HANDLE hPrinter, // 操作対象のプリンタを識別するハンドル
DWORD dwIndex, // 取得する値のインデックス
LPTSTR pValueName, // 値の名前を受け取るバッファへのポインタ
DWORD cbValueName, // 値の名前を受け取るバッファのサイズ (バイト数)
LPDWORD pcbValueName, // バッファ pValueName に格納された名前のバイト数を
// 受け取る変数へのポインタ
LPDWORD pType, // 値のタイプコードを受け取る変数へのポインタ
LPBYTE pData, // 値のデータを受け取るバッファへのポインタ
DWORD cbData, // 値のデータを受け取るバッファのサイズ (バイト数)
LPDWORD pcbData // バッファ pData に格納されたデータのバイト数を
// 受け取る変数へのポインタ
