[Dev-C++] Internet programming again

[Ben M. <ili...@at...>]

hello. I am trying to write that winsock app that i was working on the 
other day.  I want to find the IP address of the computer that is 
connecting to the server. Here is the code for the server application:

#include <winsock2.h>
#include <windows.h>
#include <iostream>
#include <fstream>
#include <string>

using namespace std;

int main ()
{
 WSADATA wsadat;
 SOCKET Socket, TempSocket = SOCKET_ERROR;
 SOCKADDR_IN SockAddr;
 SOCKADDR ConnAddr;
 ifstream infile;
 string filename = "C:\\counter.java";
 char send_str[1], recv_str[6];
 int a = 0, in_char, RetVal;

 if (WSAStartup (MAKEWORD(1,1), &wsadat) != 0)
 {
  cout << "WSAStartup failed!!!";
 }
 
 Socket = socket(AF_INET, SOCK_STREAM, 0);
 if (Socket == INVALID_SOCKET)
 {
  cout << "Socket creation failed!!!";
 }
 
 SockAddr.sin_port   = 50;
 SockAddr.sin_family = AF_INET;
 SockAddr.sin_addr.S_un.S_un_b.s_b1 = 192;
 SockAddr.sin_addr.S_un.S_un_b.s_b2 = 168;
 SockAddr.sin_addr.S_un.S_un_b.s_b3 = 1;
 SockAddr.sin_addr.S_un.S_un_b.s_b4 = 102;

 if (bind (Socket, (SOCKADDR *)(&SockAddr), sizeof (SockAddr)) == 
SOCKET_ERROR)
 {
  cout << "Attempt to bind failed!!!";
 }

 listen (Socket, 1);

 while (TempSocket == SOCKET_ERROR)
 {
  TempSocket = accept (Socket, &ConnAddr, sizeof (ConnAddr));
 }
 Socket = TempSocket;

 printf ("%s", ConnAddr.sa_data);
 while (a <= filename.length())
 {
  send_str[0] = filename[a];
  cout << send_str;
  send (Socket, send_str, 1, 0);
  ++a;
 }

 infile.open (filename.c_str());
 while (!infile.eof())
 {
  in_char = infile.get();
  send_str[0] = in_char;
  cout << send_str;
  send (Socket, send_str, 1, 0);
 }
 infile.close();

 
 while (RetVal == SOCKET_ERROR)
 {
  RetVal = recv (Socket, recv_str, 6, 0);
 }
 cout << recv_str;

 system ("pause");
 return 0;
}
The problem text is highlighted in green.  I get the error message 
"invalid conversion from 'unsigned int' to 'int *' initializing argument 
3 of 'SOCKET accept (SOCKET, sockaddr*, int*)'. But how else am i 
supposed to pass the size of the structure to the method?
