receive data buffer

基本解釋

Since you know the client will connect and immediately send data, supplying a receive buffer can make things substantially easier.
我們知道客戶端會在發(fā)出連接請求后立刻傳送數(shù)據(jù)，所以如果我們準備好接收緩沖區(qū)會使事情變得更為容易。

如果需要關(guān)閉讀取部分，則會丟棄接收緩沖區(qū)中存在的任何數(shù)據(jù)，并關(guān)閉該端的連接。
Send function takes packets from application layer into sending buffer, and the receive function takes data from receiving buffer for the application layer.
發(fā)送函數(shù)將應(yīng)用層數(shù)據(jù)包放入發(fā)送緩沖區(qū)，接收函數(shù)從接收緩沖區(qū)取得數(shù)據(jù)包。
