Ohjelman katkaiseminen escistä

do { while (! Console.KeyAvailable) { Console.WriteLine("Moi!"); } } while (Console.ReadKey(true).Key != ConsoleKey.Escape);

Oikealla C-kielellä tuo onkin vähän monimutkaisempaa. Copy–paste-koodausta muutamalla muutoksella:

----
#include <stdio.h>
#include <termios.h>
#include <unistd.h>
#include <fcntl.h>
#include <stdlib.h>
#define ESC 27

static void err_exit(const char *msg);

int main(void)
{
    int c;
    int oc = '\0';
    struct termios staryTermios, novyTermios;
    int oflags, nflags;

    if (tcgetattr(STDIN_FILENO, &staryTermios) != 0)
        err_exit("tcgetattr() failed");

    novyTermios = staryTermios;
    novyTermios.c_lflag &= ~(ICANON);
    if (tcsetattr(STDIN_FILENO, TCSANOW, &novyTermios) != 0)
        err_exit("tcsetattr() failed to set standard input");

    oflags = fcntl(STDIN_FILENO, F_GETFL);
    if (oflags < 0)
        err_exit("fcntl() F_GETFL failed");

    nflags = oflags;
    nflags |= O_NONBLOCK;
    if (fcntl(STDIN_FILENO, F_SETFL, nflags) == -1)
        err_exit("fcntl() F_SETFL failed");

    while ((c = getchar()) != ESC)
    {
    printf("Moi!\n");
    }

    if (tcsetattr(STDIN_FILENO, TCSANOW, &staryTermios) != 0)
        err_exit("tcsetattr() failed to reset standard input");

    putchar('\n');
    return 0;
}

static void err_exit(const char *msg)
{
    fprintf(stderr, "%s\n", msg);
    exit(1);
}

>>staryTermios, novyTermios;
Oletko serbialainen?

Is called recursive function calls, that go on and on untin some thing in logic stops.
- Very usual in c-code, espesially in 3D-accelerator codes...

Aika helppoa siis jos vain sen ymmärtää :D
