C++ cross-platform equivalent of Windows' QueryPerformanceCounter()

Question

To measure the execution time of some portion of C++ code on Windows, I tend to use the QueryPerformanceCounter() high-resolution timer. An example of that can be found in this VCblog post on STL performance.

With the aim of writing cross platform C++ code, what functions/classes could I use for that same purpose?

Answer 1

Assuming a modern compiler, you're probably looking for std::chrono::high_resolution_clock
