Question

C++TCP通信服务端代码问题

代码如下
#include<winsock2.h>
#pragma comment (lib,"ws2_32")

int main(int argc, char* argv[])
{
WSADATA wsaData;
WSAStartup(MAKEWORD(2,2),&wsaData);

SOCKET s = socket(PF_INET,SOCK_STREAM,IPPROTO_TCP);

sockaddr_in socketaddr;
sockaddr.sin_family = PF_INTF;
sockaddr.sin_addr.S_un.S_addr = inet_addr("127.0.0.1");
sockaddr.sin_port = htons(827);

bind(s, (SOCKADDR*)&sockaddr, sizeof(SOCKETADDR));

listen(s,1);

SOCKADDR clientAddr;
int nSize = sizeof(SOCKADDR);
SOCKET clientSock;
clientSock = accept(s,(SOCKADDR*)&clientAddr,&nSize);

send(clientSock,"hello world!\r\n",strlen("hello world!\r\n")+sizeof(char),NULL);

closesocket(clientSock);
closesocket(s);

WSACleanup();

return 0;
}

调试如下

#include<winsock2.h>
#pragma comment (lib,"ws2_32")

int main(int argc, char* argv[])
{
	WSADATA wsaData;
	WSAStartup(MAKEWORD(2,2),&wsaData);

	SOCKET s = socket(PF_INET,SOCK_STREAM,IPPROTO_TCP);
/*struct sockaddr_in {

*/
	sockaddr_in socketaddr;
	socketaddr.sin_family = PF_INET;
	socketaddr.sin_addr.S_un.S_addr =  inet_addr("127.0.0.1");
	socketaddr.sin_port = htons(827);

	bind(s, (SOCKADDR*)&socketaddr, sizeof(SOCKADDR));

	listen(s,1);

	SOCKADDR clientAddr;

	closesocket(clientSock);
	closesocket(s);

	WSACleanup();

	return 0;
}

这是修改后的代码。兄弟，打字认真点，都是单词拼写错误！！
