copied!<p>You don't access the keyboard thru pointers on Linux.</p> <p>If you are thinking of a graphical application, it uses <a href="http://en.wikipedia.org/wiki/X11" rel="nofollow">X11</a>, and its underlying protocol (which is very complex for newbies). If you are a newbie, I strongly recommend using a graphical toolkit library like <a href="http://qt.nokia.com/" rel="nofollow">Qt</a> or <a href="http://gtk.org/" rel="nofollow">GTK</a>.</p> <p>If you are thinking of a console application, I do recommend using a library like <a href="http://www.gnu.org/s/ncurses/" rel="nofollow">ncurses</a> or perhaps <a href="http://cnswww.cns.cwru.edu/php/chet/readline/rltop.html" rel="nofollow">readline</a>.</p> <p>You could indeed read the raw keyboard (since e.g. the Xorg server does), but this is painful. You'll need to learn about <a href="http://www.linusakesson.net/programming/tty/index.php" rel="nofollow">tty-s</a> and the details are painful. You'll also need to learn about the raw linux keyboard (I forgot the details, but study the Xorg server for more).</p> <p>You really should explain what you want to do. Be aware that understanding in full detail what is a tty or what is the raw keyboard takes months of work. And you should be familiar with <a href="http://linux.die.net/man/2/syscalls" rel="nofollow">linux</a> <a href="http://en.wikipedia.org/wiki/System_calls" rel="nofollow">system calls</a> before even starting.</p> <p>You should take advantage that nearly all Linux software is free; so you can study its source code.</p>
