       After  successful  completion of this routine, the results
       of using attr  in  a  call  to  any  routine  (other  than
       pthread_rwlockattr_init) are unpredictable.

RETURN VALUES    [Toc]    [Back]

       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
       value specified by attr is invalid.

ERRORS    [Toc]    [Back]
