Re: Côté Xorg...

Voici le code sans zombies :

#include <fcntl.h>
#include <stdio.h>
#include <sys/time.h>
#include <sys/wait.h>
#include <unistd.h>
/* config, avec un qwerty en exemple */
struct config {
 int key; char **cmd;
 };
static char *echo_q[] = { "echo", "touche q active", NULL };
static char *echo_w[] = { "echo", "touche", "w", "active", NULL };
static char *sleep_9[] = { "sleep", "9", NULL };
static struct config myconf[] = {
 /* { key code, cmd } */
 {16, echo_q},
 {17, echo_w},
 {18, sleep_9},
 };
int main (int argc, char *argv[])
{
 int kbd, pid;
 struct config *p;
 struct {
 struct timeval time;
 unsigned short type;
 unsigned short code;
 unsigned int value;
 } ev;
 if (argc != 2)
 return 2;
 kbd = open (argv[1], O_RDONLY);
 if (kbd < 0)
 return 1;
 loop_forever:
 read (kbd, &ev, sizeof(ev));
 if (1 == ev.type && 1 == ev.value) {
 for (p = myconf; p < myconf + sizeof (myconf) / sizeof (struct config); p++)
 if (p->key == ev.code) {
 pid = fork ();
 if (0 == pid) {
 if (0 == fork ())
 /* execlp pour exclure la recherche dans $PATH */
 execvp (p->cmd[0], p->cmd);
 return 0;
 } else {
 if (pid > 0)
 waitpid (pid, NULL, 0);
 }
 goto loop_forever;
 }
 /* pour avoir le codekey, sinon commenter: */
 printf ("%d:%d:%d\n", ev.type, ev.code, ev.value);
 }
 goto loop_forever;
}

Mort aux cons !
