RAW Sockets in C++ Windows


I want to use a RAW Socket in Visual C++.

I saw a function on Linux which is

int out = socket(AF_INET, SOCK_RAW, htons(ETH_P_ALL));

Using this code in linux we can do that, but how to use RAW SOCKET on Windows Platform because when I use this in Visual C++ I am getting Error.

Thanks in Advance.

EDIT

int out1 = socket(AF_INET, SOCK_RAW, IPPROTO_SCTP);
for (; ;)
{
    int bytesIn = recvfrom(out1, buf, 2000, 0, (sockaddr*)&server, &serverLength);
    if (bytesIn == SOCKET_ERROR)
    {
        cout << "Error Receving from Server" << WSAGetLastError() << endl;
    }
    else
    {
        cout << "MESSAGE RECV from Server " << " : " << bytesIn << endl;
    }
}

This is my code to receive the packets


Solution

  • In Windows, the closest equivalent is SOCK_RAW and you will have to use a technique to make your code cross platform compatible.

    For example use macros and extend a base generic virtual class into a windows derived class and a linux derived class, using WSAPROTOCOL for Windows and the POSIX library for Linux.

    Here is a guide on how to use raw sockets with Winsock. Here is an an answer on how to identify platform with macros.
