Depending on the terminal type, function keys usually generate a specific
sequence of characters, often starting with ESC (0x1b). For example, on my
terminal, the F1 key generates the string "\x1b\x5b\x31\x31\x7e"
Reading function keys is something very system- and OS-specific and is not
possible with only ANSI-C; you might want to ask this question in the
appropriate newsgroup that discusses programming on unix/linux. You also
might want to look into the 'curses' and/or 'termcap' libraries, which are
specially designed to handle keyboard and screen IO on unix systems.
