nanosleep

The function code is as follows: /* * Execution of the current suspend thread */ Int threadsleep (time_t sec, long nsec) { Struct timespec req, REM; // Set the length of time for suspend Req. TV _sec = (time_t) sec; Req. TV _nsec = (long) nsec; //

Sleep () and nanosleep () wake up the process after a period of sleep, but the implementation of the two is completely different. Sleep in user programs: Sleep ()Usleep ()Nanosleep () Sleep () and nanosleep () wake up the process after a period of

1. usleep is inaccurate on different hardware platforms, for example, usleep (2*1000). The result is sleep for 10 ms. Is it too much? The test code is as follows: #include #include int main(int argc,char **argv){ struct timeval oldTime, newTime;

First of all, I would like to thank the following two blogs for putting me out of a major misunderstanding: Http://www.cppblog.com/kongque/archive/2011/01/18/138765.aspx Http://blog.csdn.net/zjwoody/article/details/7882240 In one of my projects,

In the programming process, timing and latency are more or less required. There are several Timing/latency mechanisms in VxWorks. Based on the collected data and relevant documents of VxWorks, based on the learning and hands-on experiments, I would

1 taskdelayTaskdelay () provides a simple task sleep mechanism, which is also commonly used in applications that require a timing/latency mechanism. The format is status taskdelay (INT ticks/* Number of ticks to delay task */), We can see that the
