       pthread_setspecific  -  Sets  the thread-specific data value associated
       with the specified key for the current thread

	       pthread_key_t key,
	       const void *value );

       Thread-specific key that identifies the thread-specific data to receive
       value.  This key value must be  obtained	 from  pthread_key_create(3)).
       New  thread-specific data value to associate with the specified key for
       the current thread.

       This routine sets the thread-specific data value	 associated  with  the
       specified key for the current thread. If a value is defined for the key
       in this thread (the current value is not NULL), the new value  is  sub‐
       stituted	  for	it.  The  key  is  obtained  by	 a  previous  call  to

       Different threads can bind different values to the same key. These val‐
       ues  are	 typically  pointers to blocks of dynamically allocated memory
       that are reserved for use by the calling thread.

       Do not call this routine from a thread-specific data  destructor	 func‐

       Note  that  although the type for value (void *) implies that it repre‐
       sents an address, the type is being used as a “universal scalar	type.”
       DECthreads simply stores value for later retrieval.

       If  an  error  condition	 occurs, this routine returns an integer value
       indicating the type of error. Possible return values  are  as  follows:
       Successful  completion.	 The  specified	 key is invalid.  Insufficient
       memory exists to associate the value with the key.
