有偿求助： winsock lsp tcp 代理部分；详情见描述

使用 lsp->socks5 来做游戏代理，主要是自用的 步骤如下： 1：拦截 wspSocket，创建相同参数的 socket ① 2：拦截 asyncSelect 和 eventSelect。wspIoctl 并记录参数 3：connect 时用①来代替原来的 socket，如果被修改过阻塞类型那么将类型修改为阻塞；和 socks5 代理协商并发送需要代理的数据；重新设置 async,event,wspIoctl 三种事件 结果：LOL 登陆是成功的，但开始游戏后聊天室连接不上（这个没啥，还凑合）；倒计时结束开始加载对战界面的时候会提示连接服务器失败 求助：我该如何做

connect 部分代码如下：

#include "stdafx.h"

// an ip address is local address ; such as 127.0.0.1 169 192.168
bool isLocalAddr(const struct sockaddr *lpTo) {
	
}

//检查进程是否走代理
bool isProxy() {
	
}

}

int changeBlocking(SOCK_INFO *s, bool isReset = false) {
	int err = 0, ret = 0, nonBlock;

	if (isReset) {
