czesc, jestem poczatkujacy. staram sie napisac w c prosty program
zapisujacy cos do pliku. za cholere nie chce mi to dzialac (tzn.
kompiluje sie ale potem sam program nie dziala):

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

int main(int argc, char *argv[]){
 int fd;
 char wyraz[]="cos";

 if(fd = open(argv[1], O_CREAT) < 0){
 perror("open");
 exit(EXIT_FAILURE);
 }

 if(write(fd, wyraz, 3) < 0){
 perror("write");
 close(fd);
 exit(EXIT_FAILURE);
 }

 if(close(fd) < 0){
 perror("close");
 exit(EXIT_FAILURE);
 }

}


program wywala sie przy zamykaniu pliku, wypisuje ze cos z deskryptorem
fd mu sie nie podoba. uzywam knoppixa jakas wersje sprzed roku czy
dwoch.
pomozcie prosze.
pozdro.
