宕在::accept函数里，有人遇到过么？

其中调用::accept的地方是这样的：

？？？
没看懂

#3

没碰到过

#4

出现什么问题？

#5

楼主挺可怜啊，可用分是奴隶

#6

没明白。。。。只能up了！可以google下

#7

没看明白lz说的什么意思

if ((Accept = WSAAccept(Listen, (SOCKADDR*)&ClientAddr, &addr_length, NULL, 0)) == SOCKET_ERROR)
{
 printf("WSAAccept() failed with error %d\n", WSAGetLastError());
 return 0;
}

我们一般用这个函数来获取..客户端发过的信息,如果与server配对,就生成一个socket号,用于client与server的连接;









参考一下..这个。。。

看了半天WIN2K的实现代码还有逆向dll的东西，大概有点思路了。也不知道正确否。
贴子结了再说～
