10004错误！！

[tujj99]

大家帮忙看看我的程序，为什么总是出现10004错误啊！！
谢谢了！！高分送英雄！

自己up

没有人吗？

线程回调函数

1 tClientIP ClientIP; // 最好使用tClientIP *ClientIP，进行指针操作，原因是不知道
// tClientIP是否重载了运算符" = ".

2 你用的是WinSock2.2还是WinSock1.1，如果是1.1版本的，看一下哪里调用了
WSACancelBlockingCall

ps，能看看你 tClientIP 的定义吗？

[tujj99]

typedef struct tClientIP_
{
char ip[16];
unsigned short port;
SOCKET cli_socket,pro_socket;
CRITICAL_SECTION *csprosock,*csclisock;
int reserve;
}tClientIP;

[fzd999]

果然，你忘了重载运算符" = ",程序运行到ClientIP = *((tClientIP *)lpParam);的时候，并没有把数据复制过来，不相信你可以加行代码输出看一下。

两种办法，一种是按我刚才说的tClientIP *ClientIP，进行指针操作。另一种是重载运算符 =

[tujj99]

memcpy(&ClientIP,(tClientIP *)lpParam,sizeof(tClientIP));
可以吗

[fzd999]

可能可以，你试一下吧

fzd9999:
不知道你对proxy program的编写有没有心得，我现在想问你一些问题！

[fzd999]

呵呵，这方面我真没什么经验，我主要做的是系统工具开发
