You mean aside from reading the manpages?

I quote from 'man pthread_join':
When a joinable thread terminates, its memory resources (thread descriptor
and stack) are not deallocated until another thread performs pthread_join
on it. Therefore, pthread_join must be called once for each joinable thread
created to avoid memory leaks.

The alternative is setting the thread's 'detachstate' to 'detached' instead
of 'joinable', which is the default. That can be done either upon thread
creation by using the attribute parameter or in the thread routine itself
using pthread_attr_setdetachstate.
