Call a function inside a package from a stored procedure

Question

Hello:
I am kind of new to the stored procedure. Does anyone know how to call a function inside a package from another stored procedure?
I have a existing function (func_b) inside a package (pack_a) and it returns a cursor. I want to call this function from a stored procedure (proc_c) so that I use the data inside the cursor.
can I do the following in proc_c:
my_cursor1 SYS_REFCURSOR;
begin
my_cursor1 := exec pack_a.func_b
end
It will be very helpful if anyone can point me to any reading or example. Thank you very much for your information.

guys:
Thank you for your information so far. I need some more help here. I was able to run the function in my stored procedure. However, I was not able to print the result on the screen to view the cursor result, although I am using dbms_output.put_line statement inside my stored procedure.
I use the following statement to execute my stored procedure on sql*plus. I can tell the stored procedure is executed successfully, but I did see anything printed:
DECLARE TEMP VARCHAR2(100);
BEGIN PROC_LAWS_CAD_NAME_SEARCH('LPD', 'TEST DEVICE ID', 'TEST LAST NAME', 'TEST FIRST NAME', 'F', '11112009', TEMP); END;
I tried to use 'set serveroutput on' and got the following error:
ERROR:
ORA-06502: PL/SQL: numeric or value error: host bind array too small
ORA-06512: at line 1
I am kind of confused now. thank you for your help.

Here is my procedure:
create or replace
PROCEDURE PROC_SEARCH
( AGENCY_ID IN VARCHAR2,
DEVICE_ID IN VARCHAR2,
L_NAME IN VARCHAR2,
F_NAME IN VARCHAR2,
SEX IN VARCHAR2,
DOB IN VARCHAR2,
CAD_NAME_SCH_RESULT_STR OUT VARCHAR2)
AS
v_agy_id varchar2(10);
v_device_id varchar2(20);
v_l_name varchar2(25);
v_f_name varchar2(15);
v_sex varchar2(1);
v_dob date;
-- this cursor is going to be used to store a list of warrant matching
-- name search criteria
cad_srch_cursor sys_refcursor;
objSrch SEARCH_RESULT_TEMP%ROWTYPE;
BEGIN
cad_srch_cursor := SEARCH_PKG.SEARCH('TESTING', 'TESTER', null, null,null, null, getPhonetic('TESTING'));
LOOP
FETCH cad_srch_cursor INTO objSrch;
EXIT WHEN cad_srch_cursor%NOTFOUND;
--insert into SEARCH_RESULT_TEMP (name_last) values (objSrch.name_last);
CAD_NAME_SCH_RESULT_STR := objSrch.name_last;
dbms_output.put_line('First:'||objSrch.name_first||':Last:'||objSrch.name_last||':Middle:'||objSrch.name_middle);
end LOOP;
END PROC_LAWS_SEARCH;
