パラメーター

名前	型	方向	説明
Policy	DHCP_POLICY*	inout	条件を追加する対象のDHCP_POLICY構造体へのポインタ。
ParentExpr	DWORD	in	条件をぶら下げる親式のインデックス。
Type	DHCP_POL_ATTR_TYPE	in	条件で参照する属性の種別を指定するDHCP_POL_ATTR_TYPE列挙値(オプション・サブオプション・ハードウェアアドレス等)。
OptionID	DWORD	in	条件評価に用いるオプションの識別子。
SubOptionID	DWORD	in	条件評価に用いるサブオプションの識別子。該当なしなら0。
VendorName	LPWSTR	inoptional	ベンダー固有オプションを参照する場合のベンダー名。標準ならNULL可。
Operator	DHCP_POL_COMPARATOR	in	値の比較方法を指定するDHCP_POL_COMPARATOR列挙値(等しい・含む等)。
Value	BYTE*	in	比較対象の値を格納したバイト配列へのポインタ。
ValueLength	DWORD	in	Valueバッファのバイト長。
ConditionIndex	DWORD*	out	追加された条件のインデックスを受け取るDWORDへのポインタ。
