在udp中recvfrom没有收到包含数据包的校验和 [英] recvfrom in udp not receiving checksum containing packets

问题描述

我设计了一个udp应用程序，其中应用程序可以从服务器接收无限数据并将其存储在文本文件中，但问题是数据包显示在带有校验和但未收到的数据中申请方。所以我的问题是在vc ++中的recvfrom api拒绝数据包或一些额外的参数应该在绑定套接字到应用程序之前初始化？

So my question is recvfrom api in vc++ reject that packets or some extra parameters should initialise before bind socket to application?
