NAME
       MPI_Type_set_attr -  Stores attribute value associated with a key

SYNOPSIS
       int MPI_Type_set_attr(MPI_Datatype type, int type_keyval, void *attribute_val)

INPUT PARAMETERS
       type   - MPI Datatype to which attribute will be attached (handle)
       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 For-
       tran, 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.  May be an uncommitted MPI_Datatype (see MPI_Type_commit ).
       MPI_ERR_KEYVAL
	      - Invalid keyval
