The sleep() function puts the process or thread to sleep for the time in seconds that is specified in the “sec” input argument which is an unsigned integer. Once the sleep() function is called, the calling process sleeps until it times out or receives a signal. This function is often ...

想要线程休眠 1 秒钟,可以使用下面哪行代码( )。A.thread.sleep(1000);B.Thread.sleep(1000);C.thread.sleep(1)
std::sleep_for()是C++11标准中提供的休眠函数,它可以使当前线程休眠指定的时间。函数原型如下: #include <chrono>#include <thread>namespace std {template<class Rep, class Period>void sleep_for(const chrono::duration<Rep, Period>& rel_time);void sleep_for(const chrono::nanoseconds& ns);void slee...
当多个线程试图同时调用sleep函数时,可能会出现竞态条件,由于sleep函数是基于全局信号处理的,这可能导致一个线程的sleep调用被另一个线程的信号处理所中断。 解决方案:可以使用线程局部存储(ThreadLocal Storage,TLS)或者互斥锁(mutex)来确保同一时刻只有一个线程可以调用sleep。
让某个线程休眠10秒钟,应使用如下哪段代码A.Thread.sleep(10000);B.Thread.sleep(100);C.Thread.sleep(10);D.T
