Use GIO instead, it's part of the GLib namespace.

File.read () will give you a FileInputStream which you can decorate as
a DataInputStream, then you can read line by line.

------

File my_file = File.new_for_path ("myfile.data");

DataInputStream in_stream;

try {
        in_stream = new DataInputStream (my_file.read (null));
        string line;
        while (null != (line = in_stream.read_line (null, null))) {
                print (line);
        }
} catch (Error e) {
        critical (e.message);
} finally {
        in_stream.close (null);
}

------

You will have to compile with "--pkg gio-2.0". Currently you will get
some warnings about nullable parameters, since they aren't marked yet in 
the vapi bindings, which you can safely ignore.
