[En-Nut-Discussion] TCP Stream question

[Harald Kipp]

Looks good.

Well, in that case I assume that it hangs in an old
connection.

You should exit the loop in case of an error (like
dropped connection).

if (fgets(buff, sizeof(buff), stream) == 0) {
    break;
}

I'd also recommend to install ethereal, it's very
helpful.
