struct Ft_node_descriptor {

Ft_fadu_name fadu_name;

Uint16 arc_length;

Bool data_exists;

};

Set Ft_node_descriptor if you speciﬁed FT_NODE_DESC in

Ft_structure_id (Figure 3-10).

Use Ft_node_descriptor only with FTAM-2 document types to begin a

new FADU.

primitive The primitive is the speciﬁc unit that contains actual data. Set primitive to the

value speciﬁed by prim_type. See the previous table. Note that the maximum

string length is 7168 (7K) octets.

EXAMPLE: This example sets a data_element for FTAM-2 document type.

struct Ft_data_unit data_unit;

data_unit.next = NULL;

data_unit.structure_id = FT_DATA_UNIT;

data_unit.data.data_element = (struct Ft_data_element *)

malloc(sizeof (struct Ft_data_element));

data_unit.data.data_element->prim_type = FT_DE_GRAPHIC_STRING;

data_unit.data.data_element->primitive.graphic_string =

“This example shows data in a data element;”
