Wait for a thread to exit for limited time on linux

Using pthread_join(), one could wait for another thread to exit. But the pthread_join does not take a time argument, so if the other thread gets stuck and doesn't exit, the pthread_join doesn't return. Is there a way to wait for a limited time, say 5 seconds? If the other thread doesn't exit, then the calling thread could continue its own journey. Thanks a lot.

Hi shibai,

There is a long discussion about why pthread_join() has not timeout arguement.  Essentially, the library already provides enough primitives for someone to implement a timed join on their own, so none is provided. A sample implementation is also provided.
