You can either use gtk_entry_get_text to get the entire string, or you
can use gtk_editable_get_chars to get subsections of the string.  In
particular, you want to set start_pos to 0, and end_pos to -1 to
indicate the entire string.

Also, please note that while gtk_editable_get_chars duplicates the
(sub)string, gtk_entry_get_text does not.
