Linux also has a high-precision timer, that is posix_timer. I remember looking at the code when the Clock_realtime timer seems to use the RDTSC instructions, but now not sure, first put aside. In principle, you can use the RDTSC instruction in the frequency conversion, because the frequency of the CPU is also known to us, the kernel is also known when the frequency conversion. Here is my timer_create example, compile with RT library, this is the Linu

C # Calls PowerShell to control SCVMM. There are many examples on the Internet, which are relatively simple. However, the process of creating a virtual machine is a long time, so generally, during creation, you want to display the creation progress of the current Virtual Machine in real time. At that

However, deriving your own class from this class helps us control some specific aspects of the program.At the beginning, we will update our game world in a slightly different way from the DirectX example.
