TCP通訊C 實現

tcp客戶端與伺服器端通訊模型：

伺服器端實現：

#include

#include

#pragma comment(lib,"ws2_32")

using namespace std;

void main()

if ( lobyte( wsadata.wversion ) != 1 ||

hibyte( wsadata.wversion ) != 1 )

socket fd,fd_client;

struct sockaddr_in addr_server,addr_client;

char buf[100];

fd=socket(af_inet,sock_stream,0); //建立監聽套接字

addr_server.sin_family=af_inet;

addr_server.sin_addr.s_un.s_addr=htonl(inaddr_any);

addr_server.sin_port=htons(6000);

bind(fd,(sockaddr *)&addr_server,sizeof(addr_server));

listen(fd,5);

int len=sizeof(sockaddr);

while(1)

}客戶端實現：

#include

#include

#pragma comment(lib,"ws2_32")

using namespace std;

void main()

if ( lobyte( wsadata.wversion ) != 1 ||

hibyte( wsadata.wversion ) != 1 )

socket fd;

struct sockaddr_in addr;

char buf[100]="client:nihao";

fd=socket(af_inet,sock_stream,0);

addr.sin_family=af_inet;

addr.sin_addr.s_un.s_addr=inet_addr("127.0.0.1");

addr.sin_port=htons(6000);

connect(fd,( sockaddr *)&addr,sizeof(addr));

send(fd,buf,100,0);

recv(fd,buf,100,0);

cout<

closesocket(fd); }

socket實現TCP通訊

tcp是一種可靠的，面向連線的協議。在socket中，建立tcp連線的過程大致如下 伺服器端 1.初始化套接字 2.建立伺服器socket 3.將本機位址與伺服器socket繫結在一起 4.伺服器開始監聽 5.伺服器確認請求 確認之前時一種阻塞的狀態 accept 函式生成乙個新的socket。6....
