       thread.

EXAMPLES

       None.

APPLICATION USAGE

       None.

RATIONALE

       The  pthread_self()  function  provides  a  capability  similar  to the
       getpid() function for processes and the  rationale  is  the  same:  the
       creation call does not provide the thread ID to the created thread.

FUTURE DIRECTIONS

       None.
