=== Assistant: 哥们,你的思路很对,证明你已经理解 TCP“无消息边界”的本质。那我继续推进到服务器端更实战的内容。 === 哥们,你的思路很对,证明你已经理解 TCP“无消息边界”的本质。那我继续推进到服务器端更实战的内容。 ==== 书里讲到服务器用 fork() 来处理多个客户端,让每个子进程负责一个连接。 ==== 现在我问你一个关键的落地问题: 为什么在调用 <code>accept()</code> 得到 <code>connect_d</code> 后: * 父进程要关闭 connect_d * 子进程要关闭 listener_d 这两个关闭动作看起来都不是“必须的”,但实际上非常关键。 如果不这么做,会分别产生什么后果? 请分两句回答: * 不关闭 connect_d 会导致什么问题? * 不关闭 listener_d 会导致什么问题?
