This xform routine transforms a long data type into its component segments. Place the address of this routine in the dtd_xform_addr field of the IIADD_DT_DFM structure.

The shd_exp_action contains the instructions for this routine. ADW_START is the first call. Thereafter, it is examined at the return of this routine to determine the caller's next action. Set ADV_GET_DATA to have the caller provide the next section of data. If the caller receives ADW_GET_DATA and there is no more data, then it flushes any current data and does not return to this routine. ADW_FLUSH_SEGMENT indicates that the caller disposes of the output segment, and supplies a new, empty one on the next call. ADW_CONTINUE indicates that the routine is to be called again. ADW_STOP indicates that there is a problem and the process has failed; the routine is not called again.
