Socket Libraries

[cycrow]

Hi,

I would like to create a UDP client that connects and sends data to a server

I have two questions.

Will the standard Winsock library be sufficient?

if not, which socket library would you suggest i require ?

the standard winsock is sufficient...

Thank you for your reply

I really like Poco Library. Its cross compatible. And its sockets are wicked easy to use.

http://pocoproject.org/docs/

Even has socketstream to stream copiers or socketstream to std::string copiers.

Quick example (not UDP) of sending / receiving text using strings:

#include <Poco/Net/StreamSocket.h>
#include <Poco/Net/SocketStream.h>
#include <Poco/Net/SocketAddress.h>
#include <Poco/StreamCopier.h>
#include <Poco/Thread.h>
#include <string>

const char * host = "127.0.0.1";

int main()
{
    std::string outstring;
    Poco::Net::StreamSocket socket(Poco::Net::SocketAddress(host, "5221") );

    Poco::Net::SocketStream ss(socket);

    ss<<"This will get sent to the server!"<<std::endl;
    ss.shutdownsend();

    while (true)
    {
     if (socket.poll(100, SELECT_READ) == true)
    {
          if (Poco::copyToString(ss, outstring) > 0)
          {
              std::cout<<"Received "<<outstring<<" from sever"<<std::endl;
              break;
          }
    }
    Poco::Thread::sleep(100);
    }
    return 0;
}

Note: I didn't compile this. So some tweaking may be necessary. Could even remap std::cout to receive the string stream. I created a simple cout forwarder of TCP/IP using this method. It would buffer up then transmit then rebuffer. Worked pretty well. I remapped the cout to the socketstream
