       void pthread_exit(void *retval);

       Compile and link with -pthread.

       The pthread_exit() function terminates the calling thread and returns a
       value via retval that (if the  thread  is  joinable)  is  available  to
       another thread in the same process that calls pthread_join(3).

       Any  clean-up handlers established by pthread_cleanup_push(3) that have
       not yet been popped, are popped (in the reverse of the order  in  which
       they  were pushed) and executed.  If the thread has any thread-specific
       data, then, after the clean-up handlers have been executed, the  corre-
       sponding destructor functions are called, in an unspecified order.

       When a thread terminates, process-shared resources (e.g., mutexes, con-
       dition variables, semaphores, and file descriptors) are  not  released,
       and functions registered using atexit(3) are not called.

       After  the  last thread in a process terminates, the process terminates
       as by calling exit(3) with an exit status of zero; thus, process-shared
       resources  are  released  and  functions registered using atexit(3) are

       This function does not return to the caller.

       This function always succeeds.


       Performing a return from the start function of any  thread  other  than
       the  main  thread  results in an implicit call to pthread_exit(), using
       the function's return value as the thread's exit status.

       To allow other threads to continue execution, the  main  thread  should
       terminate by calling pthread_exit() rather than exit(3).

       The  value  pointed  to  by retval should not be located on the calling
       thread's stack, since the contents of that stack  are  undefined  after
       the thread terminates.

       Currently, there are limitations in the kernel implementation logic for
       wait(2)ing on a stopped thread group with a dead thread  group  leader.
       This  can manifest in problems such as a locked terminal if a stop sig-
       nal is sent to a foreground  process  whose  thread  group  leader  has
