How to execute function takes user defined type parameters as input &output

Question

Hi All,
I want to execute a function which takes user defined type as input & output parameters. But i don't know how to execute that function in pl/sql statements.
CREATE TYPE T_INPUT AS OBJECT
USER          VARCHAR2(255),
APPLICATION     VARCHAR2(255),
REFERENCE          VARCHAR2(30)
) NOT FINAL;
CREATE TYPE T_ID UNDER T_INPUT
E_ID                    VARCHAR2 (50),
CODE                    VARCHAR2 (3),
SERVICE                    VARCHAR2 (10),
C_TYPE                    VARCHAR2 (1)
) NOT FINAL;
CREATE TYPE T_OUTPUT AS OBJECT
     R_STATUS               NUMBER(10),
     E_DESC_LANG_1          VARCHAR2(1000),
     E_DESC_LANG_2          VARCHAR2(1000),
     A_REFERENCE          VARCHAR2(30)
) NOT FINAL;
CREATE TYPE T_INFO UNDER T_OUTPUT
E_INFO XMLTYPE
CREATE FUNCTION Get_Dtls
I_DETAILS IN T_ID,
O_DETAILS OUT T_INFO
RETURN NUMBER AS
END;
Here
1. T_ID is an input parameter which is a combination of T_ID + T_INPUT,
2. T_INFO is an output parameter which is a combination of T_INFO + T_OUTPUT.
Here i'll assign the T_ID values.
--- T_INPUT values
USER          = "admin";
APPLICATION     = "test";
REFERENCE     = "null";
---- T_ID values
E_ID               = "1234";
CODE               = "TTT";
SERVICE               = "NEW";
C_TYPE = "P";
Now i want to execute Get_Dtls function with T_ID,T_INFO parameters in pl/sql statements.
I want to catch the E_INFO value from T_INFO type.
How can i Do this ?
Pls Help. Thanxs in advance.
Anil.

I am very new to this. New to Oracle, PL/SQL, OO programming or testing?
set serveroutput on
declare
  tst_obj ctype;
begin
  tst_obj := pkg.proc(11);
  dbms_output.put_line('id='||tst_obj.id||'::code='||tst_obj.code||'::usage='||tst_obj.usage);
end;
/Generally I disapprove of the use of DBMS_OUTPUT (for just about anything) but it is sufficient to demonstrate the basic principle.
Really you should start using proper testing practices, ideally with an automated test harness like QUTE.
