Socket编程初学~~

#include "stdafx.h"extern char fname[100];  BOOL HttpClient(void)
{       
void LogFile(char *p);  
WSADATA ws;   
SOCKET hsocket;   
struct sockaddr_in addr;   
int iResult;   
    long lResult;   
    char strSubAddr[100],strBuffer[100];   

lResult=WSAStartup(0x0101,&ws);   
    hsocket=socket(AF_INET,SOCK_STREAM,0);   
addr.sin_family=AF_INET;   
    addr.sin_port=htons(80);   
    addr.sin_addr.s_addr=inet_addr("168.160.224.185");   
    iResult=connect(hsocket,(struct sockaddr*)&addr,sizeof(addr));   
    
if(SOCKET_ERROR==iResult) //连接失败     
    {   
WSACleanup();   
return FALSE;   
    }   
    else //连接成功
{   
strcpy(strSubAddr,"GET/99/tips/\r\n");   
strcpy(fname,"index.htm");   
iResult=send(hsocket,strSubAddr,strlen(strSubAddr),0);   
do//下载文件
{   
memset(strBuffer,NULL,sizeof(strBuffer));   
iResult=recv(hsocket,strBuffer,sizeof(strBuffer),0);   
LogFile(strBuffer);   
}while(iResult!=0);   
    }   
    WSACleanup();   
    return TRUE;     
  }   void LogFile(char*p)   
{   
FILE *fp=fopen(fname,"a+");   
    fprintf(fp,"%s\n",p);   
    fclose(fp);   
} int _tmain(int argc, _TCHAR* argv[])
{
HttpClient();
return 0;
}
编译通过了，但是总有error LNK2019的链接错误，查了半天也没搞明白~~
