Read character from keyboard

[André Wagner]

Hello,

I wonder if it's possible to read a character from the keyboard
without pressing enter...

Thank you in advance,

André

It is completely system dependent issue. Which platform do you
use?

On Unixes, you can disable tty input canononical mode or
setting it raw mode, and read 1 byte.

I've been trying to do something similar. It would appear that there is
a bug in the windows implementation of gets which causes it to block the
entire process instead of the thread.

What I'm trying to write is a server on which you can type commands
(like a prompt). So I would have two threads: one for the server
processing (the socket) and another one for the prompt. The problem is
that the socket thread won't write anything on the screen (like a
warning message) if the prompt thread is waiting for a input.

One way might be to use "select" on your socket and stdin.
