Ensure that the LO-specification structure contains the desired storage characteristics for the new smart large object.
Create an LO-pointer structure for the new smart large object and open the smart large object with the ifx_lo_create() function.
Write the data for the new smart large object to the open smart large object with the ifx_lo_write() or ifx_lo_writewithseek() function.
Save the new smart large object in a column of the database.
Deallocate the LO-specification structure with the ifx_lo_spec_free() function.
