Here is a blocking version:
char get_key()
{
static struct termio my_kb, orig_kb;
static int first = 1;
char ch;
if (first) {
first = 0;
ioctl(0, TCGETA, &orig_kb);
my_kb = orig_kb;
my_kb.c_lflag &= ~(ECHO | ISIG | ICANON);
my_kb.c_cc[4] = 1;
}
ioctl(0, TCSETAF, &my_kb);
ch = getchar();
ioctl(0, TCSETAF, &orig_kb);
return ch;
}
Note that with it installed you cannot do CTRLC. Adapt it to your need.
I also think that by using ncurses you might solve your problem a la
DOS.
Ciao, Paolo.
