パラメーター

名前	型	方向	説明
DeviceInfoSet	HDEVINFO	in	対象のデバイス情報セットを指すハンドル。
DeviceInfoData	SP_DEVINFO_DATA*	in	レジストリプロパティを取得する対象デバイスの構造体。
Property	SETUP_DI_REGISTRY_PROPERTY	in	取得するプロパティの種別。SPDRP_DEVICEDESC等のSETUP_DI_REGISTRY_PROPERTY値を指定する。
PropertyRegDataType	DWORD*	outoptional	値のレジストリデータ型(REG_SZ等)を受け取るポインタ。NULL可。
PropertyBuffer	BYTE*	outoptional	プロパティ値を受け取るバッファ(ANSI)。サイズ照会時はNULL可。
PropertyBufferSize	DWORD	in	PropertyBufferのバイトサイズ。
RequiredSize	DWORD*	outoptional	値に必要なバイト数を受け取るポインタ。不足判定に使う。NULL可。
