pthread_exit from a function called from a thread

Suppose i create a thread that ,in some point, calls a function foo(). If i call pthread_exit() from within foo, will that have as a result termination of the thread that called foo?

thanks, Nikos

Sure - thread context is unaffected by call/return. The thread IS calling pthread_exit(), no matter how long the call stack is. If 20 threads call foo then all 20 threads will exit.

Of course. Otherwise what's the point of pthread_exit in the first place. http://www.kernel.org/doc/man-pages/online/pages/man3/pthread_exit.3.html "The pthread_exit() function shall terminate the calling thread"

Yes, of course. It will also result in calling cleanup code, if any. Beware that it won't automatically clean application resources like mutexes etc. See pthread_exit() documentation for more information.
