Dear All,
Iam configuring an opensource server and i would like to know the meaning of this line..
i get an error in this line.(This is kamailio server and iam trying for instant messaging conference in it)


xdbg("script: message from [$fu ] chat0000 [$ru ] msg [$rb]\n");

It seems like a call to a debugging function, but it obviously depends on the context of the source.
You'll need to provide some more info (source file, line...) if you want any more logic responses.

well presumably xdbg is a method for logging a debug message, and it's called with a message string. Nothing tricky.

yes i shall post the entire code .. i have marked it by using *******, that s exactly where the code is..

Thanks acid Kewpie,
Sorry, i dint see ur post before replying to my earlier post.i get the following error and the error points to the previous line.

ERROR:corev_parse_spec: error searching pvar "fu"

It deffinately is a debugging function; if debug mode is activated then that line is displayed (probably in stderr).

Nothing to worry about.

but i do get errors pointing to that line.. whats ur say?..

Which errors? Where? When?

The error is that the variable '$fu' was not found.

The documentation suggests that you need to load the module 'pv' in order to gain access to the variables.

@mhernandes
The errors which i have mentioned in the post just above ur post.

I would like to know what exactly is $fu and do i need to make any changes in it .. i have posted my full cfg above.
