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?
