我的年中考核任务：求下面的重叠通讯代码，为何回调函数里打断点无法进入？

搜了下关键字RecvCompletionRoutine，你这个回调函数自己回调自己，能调得动么，总得有个触发回调的入口吧……

恩啊 ，帮忙分析下啊 兄弟

[luciferisnotsatan]

void CALLBACK CompletionROUTINE(
IN DWORD dwError,
IN DWORD cbTransferred,
IN LPWSAOVERLAPPED lpOverlapped,
IN DWORD dwFlags
);

MSDN里原型写的是CALLBACK

好像没啥关系，#define都是一样的。
WSARecv这个函数执行是否成功？

还没解决，，，求助

debug的时候
如果要进去某个函数里
是step into 不是step over
不知道这点有木有注意到。。。
