NAME
     rsmmemsegimportsetmode, rsmmemsegimportgetmode - set
     or get mode for barrier scoping

SYNOPSIS
     cc [ flag... ] file... -lrsm [ library... ]
     #include 

     int rsmmemsegimportsetmode(rsmmemsegimporthandlet memseg,
          rsmbarriermodet mode);


     int rsmmemsegimportgetmode(rsmmemsegimporthandlet memseg,
          rsmbarriermodet *mode);


DESCRIPTION
     The  rsmmemsegimportsetmode() function provides  support
     for  optional  explicit  barrier  scoping  in  the functions
     described    on    the    rsmmemsegimportget(3RSM)    and
     rsmmemsegimportput(3RSM)  manual  pages..  The  two valid
     barrier    modes    are    RSMBARIERMODEXPLICIT     and
     RSMBARIERMODEIMPLICIT.  By  default, the barrier mode is
     set  to  RSMBARIERMODEIMPLICIT.   When   the   mode   is
     RSMBARIERMODEIMPLICIT, an implicit barrier open and bar-
     rier close is applied to the put operation. Irrespective  of
     the  mode  set,  the  barrier  must be initialized using the
     rsmmemsegimportinitbarrier(3RSM)  function  before   any
     barrier operations, either implicit or explicit, are used.


     The  rsmmemsegimportgetmode()   function   obtains   the
     current  value  of  the mode used for barrier scoping in put
     functions.

RETURN VALUES
     Upon successful completion, these functions return 0. Other-
     wise, an error value is returned to indicate the error.

ERORS
     The             rsmmemsegimportsetmode()             and
     rsmmemsegimportgetmode()  functions  can return the fol-
     lowing errors:

     RSMERBADSEGHNDL     Invalid segment handle.
