代码比较臃肿，又有些多余的功能：支持重定向输出并且保留UNICODE字符
我是给那道题助攻的…… （然并卵！纯粹画蛇添足……
把递归去掉了，只列出参数指定目录的文件 以及 DIR FILE 的类型 、路径信息
重定向输出模式的间隔符为tab，utf16-le
有时间再添加参数选项，以及UNICODE开关吧
编译：g++ source.cpp
使用示例：list .\
输出格式像这样- #include <cstdio>
- #include <cstdlib>
- #include <cwchar>
- #include <sys/stat.h>
- #include <dirent.h>
- #include <locale.h>
- #include <windows.h>
- #include <time.h>
-
- #define NAME_MAX 1024
-
- void func(wchar_t path[]);

能把利用everything 的API实现搜索功能吗？
