I have been looking for this for ages. I resorted to using ncurses, but
then I was stuck with using ncurses window management (yuk). So, I tried
the code below and it doesn't seem to work as promised. I just want the
program to trap 1 keypress and continue execution.
#include <termios.h>
#include <stdio.h>
struct termios old, new;
main()
{
char c;
tcgetattr (fileno(stdin), &old); new = old;
new.c_iflag &=~(ICANON|ECHO);
tcsetattr (fileno(stdin), TCSANOW, &new);
c = getc(stdin);
tcsetattr (fileno(stdin), TCSANOW, &old);
}
All it seems to do is stop trapping my CR key??
168: {9} ./a.out
a^M^M^M^Mò
168: {10}
the ò is a CBREAK.
I'm running FreeBSD 2.1.6.
Any ideas?
