我正在尝试从终端写入文件，直到您写入“退出”。该代码可以复制，但不起作用。它甚至不写文件!我该怎么办？

void            my_script(char* name, t_Option option)
{
  FILE          *file;

  (void)option;
  while (strcmp("/stdin", "exit") != 0)
    {
      file = NULL;
      file = fopen(name,"w");
      fprintf(file, "%s", "Writing in a file !\n");
      fclose(file);
    }
}

坦克来帮忙! :)

这是我的解决方案，向你们致敬，他们提醒了我很多;)

void            my_script(char* name)
{
  FILE          *file;
  char          buff[4096];
  int           len;

  file = NULL;
  len = 0;
  file = fopen(name,"w");
  while ((len = read(0, buff, 4096)) != -1)
    {
      buff[len] = '\0';
      if (strncmp(buff, "exit", 4) == 0)
        break;
      fprintf(file, "%s", buff);
    }
  fclose(file);
}

FILE *file = fopen(name, "w");
char buff[BUFSIZ];
while(fgets(buff, sizeof(buff), stdin) && strcmp(buff, "exit\n")){
    fprintf(file, "%s", buff);
}
fclose(file);
