解決當(dāng)前的警告提示

tcp-backlog
The backlog argument defines the maximum length to which the queue of pending connections for sockfdmay grow. If a connection request arrives when the queue is full, the client may receive an error with an indication of ECONNREFUSED or, if the underlying protocol supports retransmission, the request may be ignored so that a later reattempt at connection succeeds.

backlog參數(shù)控制的是三次握手的時(shí)候server端收到client ack確認(rèn)號(hào)之后的隊(duì)列值。
