C: No such file or directory

Question

when I hard code chemin in open(chemin, O_RDONLY) to a file name, the program works, but when I leave if to open(chemin, O_RDONLY) I get No such file or directory.

Why isn't chemin in type_fichier used?

When i use printf("%s", chemin) in type_fichier I get '

int type_fichier(char * chemin) {
  int fp;
  if ((fp = open(chemin, O_RDONLY)) == -1) { perror(""); exit(0); }

  struct stat fileStat;
  if(fstat(fp, &fileStat) < 0)
    return 1;

  switch(fileStat.st_mode & S_IFMT) {
    case S_IFBLK:  printf("block device\n");            break;
    case S_IFCHR:  printf("character device\n");        break;
    case S_IFDIR:  printf("directory\n");               break;
    case S_IFIFO:  printf("FIFO/pipe\n");               break;
    case S_IFLNK:  printf("symlink\n");                 break;
    case S_IFREG:  printf("regular file\n");            break;
    case S_IFSOCK: printf("socket\n");                  break;
    default:       printf("unknown?\n");                break;
  }
}

int main(int argc, char *argv[]) {
  char fn = "file";
  type_fichier(&fn);
}

Your mistake is here, you are allocating only 1 character for fn:

char fn = "file";
type_fichier(&fn);

You probably want:

const char *fn = "file";
type_fichier(fn);
