27 * T_PRIM_HEADER
28 *
29 * Description : This type definition defines the custom specific
30 * part of a primitive. All primitives have the
31 * general format: header followed by data. The
32 * header of a primitive is changeable according to
33 * the requirements of the target system.
34 * Hints: Only the operation code opc as a USHORT value must
35 * be present. For multi-instance protocol stacks
36 * the routing information must be include in the
37 * header (T_ROUTE route).
