you might want to try the curses routines, they work under unix and there
is a djgpp version. i've attached the first part of the man page for
wgetch() (solaris 2.5.1):

curs_getch(3X)   Miscellaneous Library Functions   curs_getch(3X)

     curs_getch, getch, wgetch, mvgetch, mvwgetch, ungetch -  get
     (or push back) characters from curses terminal keyboard

     cc [ flag ... ] file ... -lcurses [ library .. ]

     #include <curses.h>

     int getch(void);

     int wgetch(WINDOW *win);

     int mvgetch(int y, int x);

     int mvwgetch(WINDOW *win, int y, int x);

     int ungetch(int ch);


     With the getch(), wgetch(), mvgetch(), and  mvwgetch()  rou-
     tines  a character is read from the terminal associated with
     the window.  In no-delay mode, if no input is  waiting,  the
     value  ERR  is  returned.   In delay mode, the program waits
     until  the  system  passes  text  through  to  the  program.
     Depending  on  the  setting  of  cbreak(), this is after one
     character (cbreak mode), or after the  first  newline  (noc-
     break  mode).  In half-delay mode, the program waits until a
     character  is  typed  or  the  specified  timeout  has  been
     reached.   Unless  noecho() has been set, the character will
     also be echoed into the designated window.
