NAME

       MPI_Type_set_attr -  Stores attribute value associated with a key

SYNOPSIS

       int MPI_Type_set_attr(MPI_Datatype datatype, int type_keyval, void *attribute_val)

INPUT PARAMETERS

       datatype
              - MPI Datatype to which attribute will be attached (handle)
       type_keyval
              - key value, as returned by MPI_Type_create_keyval (integer)
       attribute_val
              - attribute value

NOTES

       The  type of the attribute value depends on whether C or Fortran is being used.  In C, an attribute value
       is a pointer ( void * ); in Fortran, it is an address-sized integer.

       If an attribute is already present, the delete function (specified  when  the  corresponding  keyval  was
       created) will be called.

NOTES FOR FORTRAN

       All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the
       end of the argument list.  ierr is an integer and has the same meaning as the return value of the routine
       in C.  In Fortran, MPI routines are subroutines, and are invoked with the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.

ERRORS

       All  MPI routines (except MPI_Wtime and MPI_Wtick ) return an error value; C routines as the value of the
       function and Fortran routines in the last argument.  Before the value is returned, the current MPI  error
       handler  is called.  By default, this error handler aborts the MPI job.  The error handler may be changed
       with   MPI_Comm_set_errhandler   (for   communicators),   MPI_File_set_errhandler   (for   files),    and
       MPI_Win_set_errhandler  (for  RMA windows).  The MPI-1 routine MPI_Errhandler_set may be used but its use
       is deprecated.  The predefined error handler MPI_ERRORS_RETURN may be used to cause error  values  to  be
       returned.   Note that MPI does not guarentee that an MPI program can continue past an error; however, MPI
       implementations will attempt to continue whenever possible.

       MPI_SUCCESS
              - No error; MPI routine completed successfully.
       MPI_ERR_TYPE
              - Invalid datatype argument.  Additionally, this error can occur if  an  uncommitted  MPI_Datatype
              (see MPI_Type_commit ) is used in a communication call.
       MPI_ERR_KEYVAL
              - Invalid keyval
