Re: How to switch off line buffering in stdin?

["Jens B. Jorgensen" <jjorgens@bdsinc.com>]

This is a function of the tty driver. You can turn it off from the command line with
stty -raw. For how to do this in the program, just use tcgetattr/tcsetattr and make
the same settings -raw does (see the stty man page).
