[En-Nut-Discussion] freopen(..)

Hi Bernard,

This is used wrongly. The return value should not be
assigned to stdout, but only checked for failure.

freopen("uart0","r",stdin);
doesn't work?

It should, but if it's a bug you can still use
fopen() und do debug output via fprintf().

No, you can't open the same device twice. AFAIK, shared
open is not supported.
