パラメーター

名前型方向説明
pdwModifiedDWORD*inoutコンテナの変更状態を受け取るDWORDへのポインタ。列挙開始時の基準として使われる。
lpContainerInfoINTERNET_CACHE_CONTAINER_INFOA*out最初のキャッシュコンテナ情報を受け取るINTERNET_CACHE_CONTAINER_INFOA構造体へのポインタ。ANSI版。
lpcbContainerInfoDWORD*inout入力でバッファサイズ(バイト)、出力で必要サイズを受け取るDWORDへのポインタ。
dwOptionsDWORDin列挙動作を制御するオプションフラグ。通常は0を指定する。
