How to find out what code called the procedure

Question

Hi,
I'm doing an error logging api, that will log errors when it's called. What I wasn't to know is if there's a way to find out what procedure/function called the api?
One way is to pass the function as a text variable but it would be cool if the api could find out who called it.
Hope i made myself clear :-)

I think you can use DBMS_UTILITY.FORMAT_CALL_STACK (I assume that's also what Tom K is using in his utility - with a nice wrapper around it).
Look at this example:
SQL>CREATE OR REPLACE procedure p as
  2  begin
  3   dbms_output.put_line(dbms_utility.format_call_stack);
  4  end;
  5  /
Procedure created.
SQL>CREATE OR REPLACE procedure p2 as
  2  begin
  3    p;
  4  end;
  5  /
Procedure created.
SQL>CREATE OR REPLACE procedure p3 as
  2  begin
  3    p2;
  4  end;
  5  /
Procedure created.
SQL>exec p3;
