VS Code (v1.63.2),在 Linux Ubuntu 18.04 上运行,在默认设置中表示 CLOCK_MONOTONIC 未定义。 #include <time.h> ... struct timespec start_time; (void) clock_gettime(CLOCK_MONOTONIC, &start_time); 我应该如何配置 VS 代码来定义 CLOCK_MONOTONIC?
clock_gettime测代码运行时间 //函数原型: // long clock_gettime (clockid_t which_clock, struct timespec *tp); //参数列表: // CLOCK_REALTIME:系统实时时间,随系统实时时间改变而改变,即从UTC1970-1-1 0:0:0开始计时,中间时刻如果系统时间被用户该成其他,则对应的时间相应改变. // CLOCK_MONOTONIC...

int clock_gettime(clockid_tclk_id, struct timespec *tp); int clock_settime(clockid_tclk_id, const struct timespec *tp); clock_getres() 获取由clk_id制定的时钟精度。clk_id是system-wide的,因此他对所有进程都是visible的,通常会有下面的时钟: ...
and@CLKmakes it easy to find out how long it took to execute between two breakpoints. Please note that this time includes the debugger overhead. The trick is to enter@CLKin watch window, running time between two breakpoints will be added up to the current clock value. You can reset the ...

https://linux.die.net/man/3/clock_gettime Of course, you need to take care when converting from "CPU cycles" (or "timer ticks") to the desired time unit, but it can be done with integer math just fine! This is how MSVCRT computes theclock()value from the "high precision" timer ...
