Function for Exception Logging

[Patrick FICHE]

Hi community,

I would like to implement a function that would log managed Exceptions into a 
dedicated table.
For example, I have some code like :
BEGIN
Code generation exception
EXCEPTION
  WHEN OTHERS THEN Log_Error();
END;

The Log_Error function would be able to get the exception context / parameters 
to log the exception parameters into a table.
Is there any way to manage this without providing the Exception parameters as 
parameters to the Log_Error function ?

Thanks,
Patrick
