总结来说,pthread_join 超时问题通常涉及线程执行时间、同步机制和超时设置等多个方面。通过优化线程逻辑、改进同步机制和设置合理的超时时间,可以有效解决这类问题。此外,使用 pthread_timedjoin_np 等提供超时功能的函数也是处理 pthread_join 超时的一种有效方法。
= 0) { perror("pthread_create"); exit(EXIT_FAILURE); } timeout.tv_sec = 3; // 设置超时时间为3秒 timeout.tv_nsec = 0; // 使用pthread_timedjoin()等待线程结束,或超时 rc = pthread_timedjoin_np(thread_id, NULL, &timeout); if (rc == ETIMEDOUT) { printf("Thread join timed out...

pthread_timedjoin_np (pthread_t thread, void **value_ptr, const struct timespec *abstime) /* * --- * DOCPUBLIC * This function waits for 'thread' to terminate and * returns the thread's exit value if 'value_ptr' is not * NULL or until 'abstime' passes and returns an ...
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,sometimes 110...

可能的值为: │ ├── PTHREAD_CREATE_JOINABLE(可连接状态) │ └── PTHREAD_CREATE_DETACHED(分离状态) │ 分离状态的线程在结束时会自动释放资源,不需要调用 `pthread_join()`。 ├── enum __pthread_inheritsched __inheritsched │ └── 指定线程的调度属性继承方式。可能的值为: │ ├── ...
mutex互斥锁必须是普通锁(PTHREAD_MUTEX_TIMED_NP)或者适应锁(PTHREAD_MUTEX_ADAPTIVE_NP),且在调用pthread_cond_wait()前必须由本线程加锁(pthread_mutex_lock()),而在更新条件等待队列以前,mutex保持锁定状态,并在线程挂起进入等待前解锁。在条件满足从而离开pthread_cond_wait()之前,mutex将被重新加锁,以与进入...
What is altternative to phtread_timed_join_np ? I want to wait for thread temination, but not forever. If you write code for Linux only I would use pthread_timed_join_np. Yes, it's non portable. If you'd ever switch OS you will have to pay theprice. But it's is the right in...
