vdsoGettimeofdaySym uintptr vdsoClockgettimeSym uintptr ) 先通过runtime·vdsoClockgettimeSym拿物理时间,如果拿不到再通过runtime·vdsoGettimeofdaySym拿 而runtime·vdsoClockgettimeSym对应的系统调用是gettimeofday runtime·vdsoGettimeofdaySym对应的系统调用是clock_gettime 关于二者区别,可参考❲深入理解❳如何...
在一些系统调用中需要指定时间是用CLOCK_MONOTONIC还是CLOCK_REALTIME,其中CLOCK_MONOTONIC是monotonic time,而CLOCK_REALTIME是wall-time。 monotonic time字面意思是单调时间,实际上它指的是系统启动以后流逝的时间,这是由变量jiffies来记录的。系统每次启动时jiffies初始化为0,每来一个timer interrupt,jiffies加1,也就是...
