请问"找不到select.h文件"的问题如何解决?

[wswwwt]

在windows 下装了Microsoft Visual Studio 8，需要用到select时要包含进头文件“select.h”，但是找不到这个文件，请问该如何解决？

select？socket的那个？应该在<winsock2.h>中吧。

没有select.h这个文件，包含 <winsock2.h>

[wswwwt]

<winsock2.h>加了的,编译显示的错误为


error C2227: left of '->fd_count' must point to class/struct/union/generic type
type is ''unknown-type''


error C2227: left of '->fd_array' must point to class/struct/union/generic type
type is ''unknown-type''

error C2227: left of '->fd_count' must point to class/struct/union/generic type
type is ''unknown-type''

可能是自己代码的问题

[alfwolf]

你能把那段代码贴出来吗？
你fd_set如何用的？
