c - `func`完成后，线程会自动退出吗？

Question

是否需要从线程例程中显式调用pthread_exit？

示例代码:

pthread_create(&pth, NULL, (void *)func, parg);

... func() {
   ...
   //do I have to call pthread_exit() here?
   return 0;
}

Answer 1

pthread_create 文档说:

If the start_routine returns, the effect is as if there was an implicit call to pthread_exit() using the return value of start_routine as the exit status.

因此，不需要，无需显式调用它。
