如果我不关心返回值，是否需要pthread_exit？

Question

If I don't care about the return status of my thread, would I need to have a pthread_exit?

I'm wondering if there might be some subtle resource problems associated with not calling pthread_exit in my datached pthreads.

Thanks.

Answer 1

The purpose pthread_exit() is to return the exit code if any other threads that joins .

From the manual :

   Performing a return from the start function of any thread other than the main
   thread results in an implicit call to pthread_exit(), using the function's
   return value as the thread's exit status.

So, it makes no difference if you don't use it.

Answer 2

You don't have to call pthread_exit() . Returning from the thread function would work equally well, and will not leak any resources (of course, you still have to ensure that your code doesn't have any leaks).
