Re: [fpc-pascal] raw socket example

Need to change the fpsocket function call.


>From fpSocket(AF_INET,SOCK_STREAM,0)
to fpSocket(AF_INET,SOCK_RAW,0);

Is possible that the "0" needs to be changed too.

Just keep in mind that reading such socket is tricky.
There's no more IP address (as shown in the example).
The whole protocol stack needs to be handled manually.

I don't think there's any publish FPC raw-socket example.
The easiest way is to find C raw-socket example and port it to pascal.

thanks,
Dmitry
