Using dbms_metadata to retrieve the datatype and parameter name of a procedure

Question

Greeting Guru,
is there a subprogram in dbms_metadata that will retrieve the call spec of a procedure/function that ideally
if the my program spec is proc1(id1 in number, cde in varchar2, id2 out number)
if I call something like
select * from table(dbms_metadata.<subprogram> ('proc2')) ;
It gives me
id1      in      number
cde     in      varchar2
id2      out     number
any ideas/pointers ?

Hi,
Not really sure why you need it from dbms_metadata, but DESC and DBA_ARGUMENTS (dictionary view) would provide the same info. *_ARGUMENTS has lot more info in it
desc dbn
Argument Name  Type   In/Out Default
<return value> NUMBER OUT           
P1             NUMBER IN            
desc show_html_from_url
Argument Name Type     In/Out Default
P_URL         VARCHAR2 IN            
> col owner format a10
> col object_name format a10
> col argument_name format a10
> select owner, object_name, argument_name, data_type, data_length, in_out
from dba_arguments a where object_name = 'DBN'
OWNER      OBJECT_NAM ARGUMENT_N DATA_TYPE                      DATA_LENGTH IN_OUT 
HR         DBN        P1         NUMBER                                  22 IN       
HR         DBN                   NUMBER                                  22 OUT
