7、ersionEx(LPOSVERSIONINFOlpVersionInformation/pointer to version information structure);功能：获取系统的版本信息。参数：LPOSVERSIONINFOlpVersionInformation 指向 OSVERSIONINFO 的结构体。WindowsWindows 编程编程第 3 页 共 4 页这个参数也可以是 OSVERSIONINFOEX 结构体的指针（要进行强制转换）。上面的两个结构体在使用前都要对 dwOSVersionInfoSize 成员变量赋值的。返回值：成功返回 TRUE，失败 FALSE。本
8、函数的返回值为布尔类型。在 windows 提供的示例程序中，先给 GetVersionEx 传一个 OSVERSIONINFOEX 结构体指针，如果本函数返回 false。再调用，给其传一个OSVERSIONINFO 的指针。三三版本信息对照表版本信息对照表OperatinOperating g systemsystemVersVersionionnumnumberberdwMadwMajorVerjorVersionsiondwMdwMinorVinorVersioersion nOtherOtherWindows8.16.3*63OSVERSIONINFOEX.wProductType=
