You can look at the GIOChannel functions in GLib-1.3 if you are
to use GLib-1.3:

GIOStatus   g_io_channel_read_line        (GIOChannel   *channel,
					   gchar       **str_return,
					   gsize        *length,
					   gsize        *terminator_pos,
					   GError      **error);
GIOStatus   g_io_channel_read_line_string (GIOChannel   *channel,
					   GString      *buffer,
					   gsize        *terminator_pos,
					   GError      **error);

Or, more simply, you can cut-and-paste the code for:

gint     pango_read_line      (FILE        *stream,
			       GString     *str);

[ It's "publically exported" from Pango, because I wanted it in
  GTK+, but I wouldn't really advise using it since it has no
  logical reason to be in Pango ]
