C 无趣加上一点性能损失，但适用于对话框的所有组件，如清单和菜单等

您可以控制将存储在脚本文件中的脚本的所有细节，并且总体操作和流控制非常简单。

我使用了第一个选项，它工作得非常出色。非常感谢。请使用

fgets（inbuf，sizeof（inbuf），dialog）

而不是

sizeof（inbuf）-1

。请阅读手册以了解更多信息fgets@user102008-即使我知道它可能是

sizeof（inbuf）

我仍然会使用

sizeof（inbuf）-1

来防止

fgets

中的实现错误。这是一个相当简单的解决方案。一种可能的增强方法是

unlink（）

从文件系统中取消fd的链接，以便只有子级和父级可以访问它，并使用`mkstemp（）将使用的文件名随机化

pid_t pid;
char cmd[] = "dialog";
char *args[] = {"dialog", "--menu", NULL};
int status;
int fd;

if((pid = fork()) == 0)

  /* I believe dialog prints to stderr the answer chosen 
   * also you should check the return value of open()
   */
  fd = open("some_file_name", O_WRONLY | O_CREAT | O_TRUNC, 0);

  close(STDERR_FILENO);

  dup(fd);

  execvp(cmd, args);
  perror("execvp()");

   * also the file "some_file_name" should have the output
   */
