我有一个C ++应用程序(在Win32下),我需要提供性能计数器信息。我正在使用Perflib v2,因此创建了一个由CTRPP处理的清单。
我的提供程序然后调用PerfAutoInitialize和PerfCreateInstance而没有错误。
当我在Perfmon中添加计数器时,我的应用程序崩溃了。遍历反汇编显示了perflib工作线程中调用内部函数(pcwum.dll)PerfpAddOrRemoveCounter的代码。这将调用PerfpValidateCounter,它返回edi中的地址;此地址无效,当调用者解除引用时,应用程序崩溃。
如果我重新启动提供程序,计数器仍然在Perfmon中可见并正确递增。
清单如下

答案 0 :(得分:1)
我的坏。这是64/32位问题,我意识到我正在构建一个32位提供程序以在64位操作系统上运行。一切顺利,一切正常。
