Re: calling func with predef params?

These are not predefined parameters. It is pattern matching inside
function parameters definition. After expansion of #req{} by
preprocessor it is equal to (assuming that record req has 3 fields,
because i don't know exact number):

{req, _, _, _} = Req

Take a look at manual:
