问题描述

[套接字编程] [UDP 服务器]

[SOCKET PROGRAMMING] [UDP SERVER]

我正在尝试使用 UDP 服务器进行消息加密和解密.代码在这里:https://www.geeksforgeeks.org/message-encryption-decryption-using-udp-server/但我收到以下错误:

I am trying to do Message encryption and decryption using UDP server. Code is here: https://www.geeksforgeeks.org/message-encryption-decryption-using-udp-server/ But I am getting the following error:

fatal error: netinet/in.h: No such file or directory

如何解决这个问题?

推荐答案

对于 Windows 上的套接字内容，您需要 #include 并且您还需要与 -lws2_32.

For the socket stuff on Windows you need #include <winsock2.h> and you will also need to link with -lws2_32.

在程序开始时，您还需要像这样初始化库:

In the beginning of your program you will also need to initialize the library like this:

static WSADATA wsaData;
int wsaerr = WSAStartup(MAKEWORD(2, 0), &wsaData);
if (wsaerr)
  exit(1);

在像这样退出之前清理干净:

and clean before exiting like this:

WSACleanup();

其余最基本的网络功能与 *nix 平台上的相同，除了 close() 不适用于套接字，因此您需要执行 closesocket() 代替.

For the rest most basic networking functions are the same as on *nix platforms, except for close() which doesn't work on sockets, so you will need to do closesocket() instead.
