MPI_Type_set_attr - Stores attribute value associated with a key
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.
