问题 How does "powercfg -energy" command detect the requested timer resolution of each individual program running at the time? I imagine one way would be injecting into each of running processes and inside that process calling timeEndPeriod for each increased resolution (values 1-15) in a loop over these resolutions and checking whether the timeEndPeriod call for a current resolution returns TIMERR_NOCANDO or TIMERR_NOERROR (note: these return values are NOT correspondingly false and true ) . And

How to get unique machine signature without WMI?

阅读更多关于 How to get unique machine signature without WMI?

I know that a question has already been asked about generating a unique ID for a machine but my question is slightly different. I want to know whether there are any other methods (API calls?) to get hardware information and NOT use WMI. I understand from MSDN that WMI is introduced in Win2000 so it doesnt seem to be available in Win98.

What is the Equivalent of Windows WMI for MacOS C++ Development?

阅读更多关于 What is the Equivalent of Windows WMI for MacOS C++ Development?

I have a C++ application that gets detailed system information (processor type, available disk space, other hardware profile info) on Windows using WMI. I want to perform the same type of operations on OSX 10.5+. What is the equivalent API or interface for MacOS? Links to API documentation or tutorials are very welcome. You can query most of that information through the system_profiler executable. Apple's example for querying such informations involves a popen call to it, so I guess it's the way to go. 来源： https://stackoverflow.com/questions/3613369/what-is-the-equivalent-of-windows-wmi-for
