How to return "Table of Number" etc from Oracle procedure into C++

From C++ how can I capture and iterate through the output results of an Oracle PL/SQL stored procedure that returns data as "TABLE of NUMBER(7)", or "TABLE of VARCHAR2(100)" etc?  I haven't found a clear example or documentation that details the accessing data returned as tables.
   I'm using the MS VC9++ (VS2008 SP1) with the Oracle 11.2 32-bit Instant Client. At this point I need to stay at these versions to not risk breaking the compilation of a much larger project with a lot of legacy hardware and drivers.  I've tried many variations that don't compile, or give runtime errors. Running OTT has prove problematic as the TYPE definitions only exist when the procedure is run.
   I'm currently using the OCCI interface but am open to using C++ .net if it will coexist with the current C++ code.

PL/SQL package definition

create or replace PACKAGE          "CARRIERPKG" AS
    TYPE tcarrier_site     is TABLE of NUMBER(7)      INDEX BY BINARY_INTEGER;
    TYPE tpart_serial      is TABLE of VARCHAR2(100)  INDEX BY BINARY_INTEGER;
    TYPE tpart_rtn_msg     is TABLE of VARCHAR(200)   INDEX BY BINARY_INTEGER;
   
 
      PROCEDURE get_parts_v12
      (p_carrier_serial	  IN  phase2.carrier_site.carrier_serial_num%TYPE,
       p_part_num         IN  phase2.part_info.PART_NUM%TYPE,
       p_carrier_type     IN  phase2.carrier_type.id%TYPE,
       carrier_site       OUT NOCOPY tcarrier_site,
       part_serial        OUT NOCOPY tpart_serial,
       rtn_msg            OUT NOCOPY tpart_rtn_msg);
