socket cs模型基礎架構,server及client
基本介紹
- 中文名：套接字
- 外文名：socket
Client,server,
Client
源碼
#include "stdafx.h"
#include <Winsock2.h>
#pragma comment(lib,"ws2_32")
#include <stdio.h>
#define PORT 1129
#define ADDRESS "127.0.0.1"
int main()
{
//載入winsock庫
WSADATA wsaData;
WORD sockVersion = MAKEWORD(2,2);
if(WSAStartup(sockVersion,&wsaData)!=0)
return 0;
//創建套接字
SOCKET sClient = socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
if(sClient==INVALID_SOCKET)
