相信做过游戏多开的朋友就会发现，很多游戏普遍使用互斥mutex来防止程序多开，说实话这种方式已经非常OUT了。但是由于时间和技术的沉淀关系，留下来的游戏依然会存在这种方式。 最近接触到一款游戏是N前非常火热的对战游戏，可以称为经典之作；它就是用的Mutant来实现游戏防止多开的，一般咱们测试的时候都是用Xuetr来关闭游戏，但是要作为成品发布不可能要求客户拿Xuetr来列进程对象句柄，关句柄吧~
网上搜索了半天都没有找到枚举进程句柄的例子，经过群里的大牛提点指到 ZwQuerySystemInformation SystemHandleInformation 可以实现句柄枚举功能；经过一番搜索编码测试 于是有了本文代码；

CLOSEMUTEXNAME 为互斥的句柄名称，需要为宽字节；
程序执行结果如下：
为了测试方便直接把程序写入了main函数中，大家使用的时候稍微修改便可， 不过！得理解程序意思才行啊。 copy代码不做思考的程序员不是好裁缝！
