For details on FNC_SetStructuredAttribute, FNC_SetStructuredAttributeByNdx, FNC_GetStructuredResultLobAttribute, and FNC_GetStructuredResultLobAttributeByNdx, see C Library Functions.

The following code excerpt sets the attribute value of a structured UDT:

void setX( UDT_HANDLE *pointUdt,
           INTEGER    *val,
           UDT_HANDLE *resultPoint,
           char        sqlstate[6])
{
    INTEGER x;
    INTEGER newval;
    int nullIndicator;
    int length;
    /* Set the x attribute of the result point. */
    nullIndicator = 0;
    newval = *val;
    FNC_SetStructuredAttribute(*resultPoint, "x", &newval,
                                nullIndicator, SIZEOF_INTEGER);

    ...
