===== 4. 服务器高级话题与错误处理 ===== | 我的总结 | 补充细节| | :--- | :--- | | '''端口重用：''' 服务器关闭后立即重启时，bind() 调用可能会失败（"Address already in use"），需设置 '''SO\_REUSEADDR 选项'''。 | '''延时原因：''' 绑定端口有延时，在服务器关闭后的接下来约30秒内，操作系统不允许任何程序再绑定它 。 | | '''处理多客户端：''' 使用 fork() 克隆一个独立的子进程来处理与客户端的对话。 | '''进程数量控制：''' 如果预期有大量客户端连接，需要'''控制创建子进程的上限''' 。 |
