[Serdev] How can I pass uri to a module?

[Kannaiyan Natesan]

I want to pass uri from the configuration file to the module.

mymodule(uri);

and I want to take the uri and process further.

However i endedup in the config file error when i just pass uri as a 
parameter.

I tried to get the uri from sip_msg structure, but it is always null.
any clues how this can be done. thanks.
