#include <windows.h>

DWORD InternetSetCookieExW(

パラメーター

名前型方向説明
lpszUrlLPCWSTRinCookieを設定する対象URLを指すワイド文字列。スキームとホストからCookieの適用範囲が決まる。
lpszCookieNameLPCWSTRinoptional設定するCookieの名前。NULLの場合はlpszCookieDataに「name=value」形式の文字列を指定する。
lpszCookieDataLPCWSTRinCookieのデータ本体。属性付きの「value; expires=...; path=...」等を指定できる。
dwFlagsDWORDinCookieの種別を示すフラグ。INTERNET_COOKIE_THIRD_PARTYやEVALUATE_P3P等を組み合わせる。
dwReservedUINT_PTRinoptional将来の拡張用の予約引数。常に0を指定する。

戻り値の型: DWORD
