pthread_join ___pthread_join(pthread_tthreadid,void**thread_return) 等待一个threadid的线程结束 pthread_join内部依靠__pthread_clockjoin_ex实现,用于实现线程的同步等待功能。 它允许主线程等待指定的目标线程终止,同时还支持根据给定的时间限制进行等待。函数的逻辑涉及到检测线程的状态、等待线程退出,以及释放资...
int __pthread_timedjoin_np_time64(pthread_t thread, void **retval, const struct timespec *abstime); thread: 要等待的线程标识符。 retval: 指向一个指针的指针,用于存储线程退出时的返回值。如果不需要此返回值,可以传递 NULL。 abstime: 指向一个 timespec 结构,指定等待线程终止的绝对时间。如果线程...
3个线程需要同步 pthread_barrier_init(&barrier, nullptr, 3); // 创建线程 pthread_create(&t1, nullptr, waitAtBarrier, nullptr); pthread_create(&t2, nullptr, waitAtBarrier, nullptr); pthread_create(&t3, nullptr, waitAtBarrier, nullptr); // 等待线程结束 pthread_join(t1, nullptr); ...
Hi friends, I seems that i have buggy implementation of pthread_timedjoin_np. Although linux does not documented this function yet ( seehttp://www.kernel.org/doc/man-pages/missing_pages.html), I suspectthat on my installationthis function does not work properly because it returns sometimes 0...

线程的运行属性pthread_attr_t主要包括:__detachstate,表示新线程是否与进程中其他线程脱离同步,如果置位则新线程不能用pthread_join()来同步,且在退出时自行释放所占用的资源,缺省为PTHREAD_CREATE_JOINABLE状态,这个属性可以在线程创建并运行以后用pthread_attr_setdetachstate来设置;__schedpolicy,表示新线程的调度策...
