Can a signal pass more than one argument?

[Samson Melamed <elist jaguar dyn ml org>]

I have a menu item 'Add', which calls an 'add' function, which I would
like to get several from several gtk_entry's and then print it out. 

What I'd like to know, if there is a way to a callback function to get
more than just one other argument.  E.g. can I send in three 'gpointer*'s
instead of just one?  Is there a function other than gtk_signal_connect
that will do this?  Thanks a lot.
