You get the GtkEntry contents by:
    const gchar* gtk_entry_get_text             (GtkEntry *entry);

It is a GTK API function, http://www.gtk.org/api/.
To call it you need a handle to your entry.
You can get it by lookup_widget function,
if using glade-built code.

You can also assign callback 'changed' to that entry
and copy contents somewhere every time its called.
Then you get GtkEntry* as a parameter.
