跪求一关于《网络编程》的聊天问题!!!!急急急急急。。。。。。。谢谢!!!
这一段有问题 即服务端有问题#include <Winsock2.h>
#include <stdio.h>
void main()
{
WORD wVersionRequested;
WSADATA wsaData;
int err;
wVersionRequested=MAKEWORD(1,1);
err=WSAStartup(wVersionRequested,&wsaData);
if(err!=0)
{
return;
}
if(LOBYTE(wsaData.wVersion)!=1||
HIBYTE(wsaData.wVersion)!=1)
{
WSACleanup();
return;
}
SOCKET sockSrv=socket(AF_INET,SOCK_DGRAM,0);
SOCKADDR_IN addrSrv;
addrSrv.sin_addr.S_un.S_addr=htonl(INADDR_ANY);
addrSrv.sin_family= AF_INET;
addrSrv.sin_port=htons(6000);
bind(sockSrv,(SOCKADDR*)&addrSrv,sizeof(SOCKADDR));
char recvBuf[100];
char sendBuf[100];
char tempBuf[100];
SOCKADDR_IN addrClient;
int len=sizeof(SOCKADDR);
while(1)
{
printf("Please input data:\n");
gets(sendBuf);
sendto(sockSrv,sendBuf,strlen(sendBuf)+1,0,(SOCKADDR*)&addrClient,len);
recvfrom(sockSrv,recvBuf,100,0,(SOCKADDR*)&addrClient,&len);
if('q'==recvBuf[0])
{
sendto(sockSrv,"q",strlen("q")+1,0,(SOCKADDR*)&addrClient,len);
printf("Chat end!\n");
break;
}
sprintf(tempBuf,"%s say: %s",inet_ntoa(addrClient.sin_addr),
recvBuf);
printf("%s\n",tempBuf);
closesocket(sockSrv);
WSACleanup();
}

下面的是客户端 可以运行的!

--------------------编程问答-------------------- 你的服务器端的addrClient都没有初始化,消息能发的出去么? --------------------编程问答-------------------- 你的服务器端的整个流程有问题
