finding the beginning of the current line in a text buffer

[Rajarshi Guha <rajarshi presidency com>]

Hi,
  I'm using a GtkTextView and its associated GtkTextBuffer. What I need
to do is to insert a character at the beginning of the current line when
the user presses a button.

I see that I need to use gtk_text_buffer_get_iter_at_line () but how do
I get the current line number in the text buffer?

Thanks,
