服务端：

#include

int main()

{

int sockClient;

struct sockaddr_in addrSrv;

sockClient = socket(AF_INET,SOCK_DGRAM,0);

addrSrv.sin_addr.s_addr=inet_addr("127.0.0.1");

addrSrv.sin_family=AF_INET;

addrSrv.sin_port=htons(6000);

sendto(sockClient,"Hello World",strlen("Hello World")+1,0,(struct sockaddr*)&addrSrv,sizeof(struct sockaddr));

sockClient);

}

客户端：

#include

int main()

{

int sockSrv;

struct sockaddr_in addrSrv;

int len;

recvBuf[100];

scanf("%s",recvBuf);

struct sockaddr_in addrClient;

sockSrv = socket(AF_INET,SOCK_DGRAM,0);

addrSrv.sin_addr.s_addr = htonl(INADDR_ANY);

addrSrv.sin_family = AF_INET;

addrSrv.sin_port = htons(6000);

sockSrv, (struct sockaddr *)&addrSrv, sizeof(struct sockaddr));

len = sizeof(struct sockaddr);

memset(recvBuf, 0, 100);

recvfrom(sockSrv, recvBuf, 100, 0, (struct sockaddr *)&addrClient,&len);

printf("客户端的IP地址:%s\\r\n",inet_ntoa(addrClient.sin_addr));

printf("Client data is:%s\\n",recvBuf);

sockSrv);
