パラメーター

名前	型	方向	説明
DeviceInfoSet	HDEVINFO	in	対象デバイスを含むデバイス情報セットのハンドルを指定する。SetupDiGetClassDevs等で取得する。
DeviceInfoData	SP_DEVINFO_DATA*	in	情報セット内の特定デバイスを示すSP_DEVINFO_DATA構造体へのポインターを指定する。
CustomPropertyName	LPCWSTR	in	取得するカスタムプロパティ名を表すNULL終端のワイド文字列を指定する。レジストリのHardwareID配下の値名に相当する。
Flags	DWORD	in	取得方法を制御するフラグ。ハードウェアキー/デバイスキーの選択(DICUSTOMDEVPROP_MERGE_MULTISZ等)を指定する。
PropertyRegDataType	DWORD*	outoptional	取得した値のレジストリデータ型(REG_SZ等)を受け取るDWORDへのポインター。不要ならNULL可。
PropertyBuffer	BYTE*	out	プロパティ値を受け取るバッファーへのポインター。サイズ問い合わせ時はNULL可。
PropertyBufferSize	DWORD	in	PropertyBufferのサイズをバイト単位で指定する。
RequiredSize	DWORD*	outoptional	実際に必要なバッファーサイズをバイト単位で受け取るDWORDへのポインター。不要ならNULL可。
