Web1. The following structure is used by gettimeofday (2), among others: struct timeval { time_t tv_sec; suseconds_t tv_usec; }; The tv_sec member represents the elapsed time, in whole seconds. The tv_usec member captures rest of the elapsed time, represented as the number of microseconds. 2. The following structure is used by nanosleep (2), among ... Web我们为其建立一个信号处理函数，执行相应的处理逻辑。信号属于异步事件，在多线程条件下，还需考虑信号重入问题。Linux下的3组IO复用函数都带有超时参数，因此他不仅能统一处理信号和IO事件，也可以处理定时事件。redis中是采用IO复用来进行定时任务的。 WebNov 17, 2024 · A struct itimerval variable has two fields: it_value is a struct timeval field that contains the time until the timer next expires and a signal is sent. If this is 0, the timer is disabled. it_interval is another struct timeval field containing the value to which the timer will be reset after it expires. If this is 0, the timer will be disabled ... lower self discipline
