GDB handles Ctrl-D differently. It doesn't close the input on
the
first one, it waits for the second one and then exits. After
the first
one it acts like you typed 'quit', which asks you if you
really want
to quit when there's a program still running.
That's because gdb uses libreadline (or something along those
lines)
with cbreak, so it can intercept control characters without
them getting
interpreted by the terminal. This requires manual control of
terminal
functions, which is something outside the scope of readf().
(You'd be
better off writing your own terminal handling from scratch, if
that's
what you want.)

Ah, nice to know. Thanks.
