c - 是否有必要调用 pthread_exit()

Question

我创建了 2 个没有任何 pthread_exit() 的线程，并添加了 2 个 pthread_join()
有什么问题吗？是否可以？

Answer 1

您不需要调用 pthread_exit。线程函数可以在完成时简单地返回。

来自手册页:

An implicit call to pthread_exit() is made when a thread other than the thread in which main() was first invoked returns from the start routine that was used to create it. The function's return value serves as the thread's exit status.
