小弟不才 寫了個模擬器 在標紅的地方讀不到東西了 回傳值是-1 getlasterror回傳的是10038
各路大神新手求解 只是寫了個很簡單的單連接 為什么socket就斷了呢
uj5u.com熱心網友回復：
補充一下 前面都是收發正常 socket可用 到了標紅處 就10038了uj5u.com熱心網友回復：
你這就是個無效的socket，沒有accept，也沒有connect，能recv的話，你才是大神uj5u.com熱心網友回復：
你這就是個無效的socket，沒有accept，也沒有connect，能recv到資料話，你才是大神uj5u.com熱心網友回復：
大神 那為何前面能收能發
uj5u.com熱心網友回復：
面向連接的Socket Server的簡單實作uj5u.com熱心網友回復：
accept要寫while回圈里面uj5u.com熱心網友回復：
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.
