Returning structure from dll to pl/sql

Question

hi
we have a problem regarding how to return structure of arrays from c dll. It may be possible with oci programing . Is it possible with simple c program using oracle object types or by pl/sql records .
We are having oracle 8i running on windows 2000 server
Thanks,

Oracle9 i JDBC Developers Guide and Reference(page 21-16):
It is not feasible for Oracle JDBC drivers to support calling arguments or return
values of the PL/SQL RECORD, BOOLEAN, or table with non-scalar element types.
However, Oracle JDBC drivers support PL/SQL index-by table of scalar element
types. For a complete description of this, see "Accessing PL/SQL Index-by Tables"
on page 16-21.
As a workaround to PL/SQL RECORD, BOOLEAN, or non-scalar table types, create
wrapper procedures that handle the data as types supported by JDBC. For example,
to wrap a stored procedure that uses PL/SQL booleans, create a stored procedure
that takes a character or number from JDBC and passes it to the original procedure
as BOOLEAN or, for an output parameter, accepts a BOOLEAN argument from the
original procedure and passes it as a CHAR or NUMBER to JDBC. Similarly, to wrap a
stored procedure that uses PL/SQL records, create a stored procedure that handles
a record in its individual components (such as CHAR and NUMBER) or in a structured
object type. To wrap a stored procedure that uses PL/SQL tables, break the data
into components or perhaps use Oracle collection types.
