}小弟不才 写了个模拟器 在标红的地方读不到东西了 返回值是-1 getlasterror返回的是10038
各路大神新手求解 只是写了个很简单的单连接 为什么socket就断了呢 

Answer 1

补充一下 前面都是收发正常 socket可用 到了标红处 就10038了

Answer 2

你这就是个无效的socket，没有accept，也没有connect，能recv的话，你才是大神

Answer 3

你这就是个无效的socket，没有accept，也没有connect，能recv到数据话，你才是大神

Answer 4

面向连接的Socket Server的简单实现

Answer 5

accept要写while循环里面

Answer 6

WSAENOTSOCK 
(10038) 
Socket operation on non-socket. 
An operation was attempted on something that is not a socket. Either the socket handle parameter did not reference a valid socket, or for select, a member of an fd_set was not valid.
