Oh. I assumed too much. If you are going to code in Unix, please consider reading/referring to one of these books - the calls I mentioned are all explained with examples:
Michael Kerrisk 'The Linux Programming Interface: A Linux and UNIX System Programming Handbook'
Stevens & Rago 'Advanced Programming in the UNIX Environment, 3rd Edition'

Hi,
I need a way to detect the up and down arrow key inputs for my program. I do not want to wait for the return key to be entered(so that rules out getch() and family). Also I need to process several of these inputs in parallel, by servicing each request with a thread.
Is that possible?

exkeys
exkeys(3alleg4) Allegro manual exkeys(3alleg4)
NAME
exkeys - How to get input from the keyboard in different ways. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
Example exkeys
DESCRIPTION
This program demonstrates how to access the keyboard. The first part shows the basic use of readkey(). The second part shows how to extract
the ASCII value. Next come the scan codes. The fourth test detects modifier keys like alt or shift. The fifth test requires some focus to
be passed. The final step shows how to use the global key array to read simultaneous key presses. The last method to detect key presses
are keyboard callbacks. This is demonstrated by installing a keyboard callback, which marks all pressed keys by drawing to a grid.
