[Click] Use of READ_PARAM ?

[remi.clavier at orange-ftgroup.com]

An element manage an Hashtable of objects.
I want to write a read handler where the return string is dependant of a given object identified by a key.
For that I need to read the key of the relevant object and pass it to the read_handler callback function (something like a write/read handler)

It is possible?
It's such element written in the element directory?

How to implement it? Perhaps the READ_PARAM flag may be used, but how?

I wish a very nice 2010 year faor all the participant of the list

Thanks for help
