type
: Data type to which the attribute is attached (handle).type_keyval
: Key value (integer).
attribute_val
: Attribute value, unless flag = falseflag
: "false" if no attribute is associated with the key (logical).ierror
: Fortran only: Error status (integer).
For the given data type, :ref:`MPI_Type_get_attr` returns an attribute value that corresponds to the specified key value.
