C ++跨平台等同于Windows的QueryPerformanceCounter（） [英] C++ cross-platform equivalent of Windows' QueryPerformanceCounter()

问题描述

要测量Windows上某些部分C ++代码的执行时间，我倾向于使用 QueryPerformanceCounter（） 高分辨率定时器。有关示例，请参见此VCblog帖子关于STL性能。

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.

为了编写跨平台 C ++代码，我可以使用什么函数/类来达到同样的目的？

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

推荐答案

假设现代编译器，你可能需要 std :: chrono :: high_resolution_clock

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