   *  Status Codes for these errors
   *
   *
   *  E_OK - Normal Completion 
   *
   *  E_NOMEM - Insufficient memory (Memory for control block and/or user
   *            stack cannot be allocated) 
   *
   *  E_ID - Invalid ID Number (tskid was invalid or could not be used) 
   *
   *  E_RSATR - Reserved attribute (tskatr was invalid or could not be used) 
   *
   *  E_OBJ - Invalid object state (a task of the same ID already exists) 
   *
   *  E_OACV - Object access violation (A tskid less than -4 was specified 
   *           from a user task. This is implementation dependent.) 
   *
   *  E_PAR - Parameter error (pk_ctsk, task, itskpri and/or stksz is invalid) 
   *
   *  E_NOEXS - Object does not exist (the task specified by tskid does not
   *            exist) 
   *
   *  E_CTX - Context error (issued from task-independent portions or a task 
   *          in dispatch disabled state) 
   *
   *
   *
   *  Network Specific Errors  (ITRON calls these Connection Function Errors)
   *
   *  EN_OBJNO - An object number which could not be accessed on the target
   *             node is specified. 
   *
   *  EN_CTXID - Specified an object on another node when the system call
   *             was issued from a task in dispatch disabled state or from
   *             a task-independent portion 
   *
   *  EN_PAR - A value outside the range supported by the target node and/or 
   *           transmission packet format was specified as a parameter
   *           (a value outside supported range was specified for exinf,
   *           tskatr, task, itskpri and/or stksz) 
   *
   *  EN_RPAR - A value outside the range supported by the requesting node 
   *            and/or transmission packet format was returned as a return 
   *            parameter (a value outside supported range was returned for
