パラメーター

名前	型	方向	説明
DirectoryPath	LPCSTR	inoptional	INFを検索するディレクトリパス(ANSI)。NULLで既定のINFディレクトリを使う。
InfStyle	INF_STYLE	in	対象とするINFスタイル(旧形式/Win4形式)を示すフラグ。
ReturnBuffer	LPSTR	outoptional	見つかったINFファイル名のマルチ文字列を受け取るバッファ(ANSI)。NULLでサイズ取得のみ可。
ReturnBufferSize	DWORD	in	ReturnBufferのサイズ(文字数)。
RequiredSize	DWORD*	outoptional	必要なバッファサイズを受け取る出力ポインタ。NULL可。
