Does "at the keyboard" mean "on the console" ?

This post is very difficult to understand for some reason. Maybe I'm being thick.

Quote:
I'm trying to write a shell script that runs periodically
This implies a regular cron job or some other automated job (hence the reply in post #2). This is clearly? not the case.

Best I can suggest is running the unix command "tty" when "at the keyboard". Hopefully it will reply "/dev/console". If it does, we have a simple way of distingishing where we are.


Btw. It would really help if you answered the questions.

NAME
glutKeyboardFunc - sets the keyboard callback for the current window. SYNTAX
void glutKeyboardFunc(void (*func)(unsigned char key, int x, int y)); ARGUMENTS
func The new keyboard callback function. DESCRIPTION
glutKeyboardFunc sets the keyboard callback for the current window. When a user types into the window, each key press generating an ASCII character will generate a keyboard callback. The key callback parameter is the generated ASCII character. The state of modifier keys such as Shift cannot be determined directly; their only effect will be on the returned ASCII data. The x and y callback parameters indicate the mouse location in window relative coordinates when the key was pressed. When a new window is created, no keyboard callback is initially registered, and ASCII key strokes in the window are ignored. Passing NULL to glutKeyboardFunc disables the generation of keyboard call- backs. During a keyboard callback, glutGetModifiers may be called to determine the state of modifier keys when the keystroke generating the call- back occurred. Use glutSpecialFunc for a means to detect non-ASCII key strokes. SEE ALSO
