C++ Windows 2012上的CreateMutex，错误代码错误\u访问被拒绝

我正在尝试使用以下代码在Windows 2012上创建互斥：

CreateMutex(securityAttributes, FALSE, TEXT("Global\\test"));

它总是给出错误代码5（错误访问被拒绝）

我试图创建我发现的安全属性，但没有成功。 请注意，此代码适用于Windows 7

这里有什么问题

我想创建可由windows服务（系统帐户）和用户帐户使用的全局互斥体。

似乎问题在于安全属性不正确。现在可以了。下面是创建安全属性的代码

可能已经存在具有该名称的互斥体，并且具有限制性权限。请尝试一个更独特的名称。我也尝试过。互斥锁是由服务还是用户创建的？服务和用户。。
