Terminates the current thread.

If another thread is waiting for us using g_thread_join() then the waiting thread will be woken up and get retval as the return value of g_thread_join().

Calling g_thread_exit() with a parameter retval is equivalent to returning retval from the function func, as given to g_thread_new().

You must only call g_thread_exit() from a thread that you created yourself with g_thread_new() or related APIs. You must not call this function from a thread created with another threading library or or from within a GThreadPool.
