C-被分离线程是否会在主线程return时被kill？

Question

针对pthread，若线程被分离，它是否会在主线程return，或者kill掉进程时也被kill掉？

Answer 1

应该是会被kill掉

The detached attribute merely determines the behavior of the system when the thread terminates; it does not prevent the thread from being terminated if the process terminates using exit(3) (or equivalently, if the main thread returns).

http://linux.die.net/man/3/pthread_detach

Any of the threads in the process calls exit(3), or the main thread performs a return from main(). This causes the termination of all threads in the process.
