I have been having problems with making curses recognize the arrow keys from
any keyboard under ULTRIX. I have tried anything I could, so now in
desparation I am asking the net wizards for help.
According to the "Guide to Curses" manual, the function call keyboard()
makes the function keys return one octal value rather than a sequence of
escape characters. For instance, the up-arrow key should return KEY_UP
(defined in /usr/include/cursesX.h as 0403) rather that something like
^[OA.
On other ( != ULTRIX ) machines this works just fine. However on my
DECstation 3100 running ULTIRX the function keys continue returning
stuff like ^[OA rather than the octal code regardless of the setting
of keypad().
Is there a magic incantation that will fix my problem?
Here is a minimal program (test.c) which reads the keyboard and echos the
pressed keys. It returns three characters for each pressing of an arrow key.
I have compiled the program with
cc -O -o test test.c -lcursesX
and
cc -O -o test test.c /usr/lib/termcap.o -lcursesX
with identical results. What gives?
/* ------------------------ test.c -------------------------------------- */
#include <cursesX.h>
main()
{
char c;
initscr();
cbreak();
noecho();
keypad(stdscr, TRUE);
printw("Press any key to test. Press 'q' to quit.\n");
refresh();
while ( ( c = getch() ) != 'q' ) {
printw("You pressed %c, Octal: %o\n", c, c);
refresh();
}
endwin();
}
/* ------------------------- end of test.c ---------------------------- */
