"stty: standard input: Inappropriate ioctl for device" when running program
 
I am getting the message "stty: standard input: Inappropriate ioctl for device" when running a program. Does this mean that the program is not running from an interactive console ? The program is periodically attempting to read from standard input on one of its threads via kbhit() and getch().

The standard input isn't a terminal. You can check this, if you know the PID:
Code:
ls -l /proc/pid/fd/0

Are you saying the error message is occurring because the standard input is not a terminal and it needs to be a terminal if I am using kbhit() and getch() in the program ?

Why would you use them if it weren't a terminal?
You can use 'isatty(0)' in your program to determine if stdin is a terminal or not.
