libncurses and getch ()

[James Morrison <rocketmail_com@rocketmail.com>]

 Hi,

 I've been trying to find out why pptop doesn't get characters with getch ()
from
libncurses.  I think I traced to problem code down to something that resembles
the following program.

#include <unistd.h>
#include <fcntl.h>
#include <stdio.h>
#include <termios.h> 

int main (int argc, char *argv[]) 
{
        char q;
        struct termios info;
        int n, in = fileno (stdin);;

        fcntl (in, F_SETFL, fcntl (in, F_GETFL, 0) | O_NONBLOCK);
                                     
        tcgetattr (in, &info);
        info.c_lflag &= ~ICANON;
        info.c_iflag &= ~ICRNL;
        info.c_lflag |= ISIG;
        info.c_cc[VMIN] = 1;
        info.c_cc[VTIME] = 0;

        tcsetattr (in, TCSADRAIN, &info);
        while (q != 'q')
        {
                n = read (fileno (stdin), &q, 1);
                printf ("%d\n", n);
                sleep (1);
        }
        return q;
}

  The problem is that this program works.  Anyone have any ideas?
