Getting CFReadStreamRef and CFWriteStreamRef from CFSocket

-(void) createSocket
{
    int sockfd;
    struct sockaddr_in servaddr;
    char sendline[] = "hello world";

    char addr[] = “10.0.0.1";


    sockfd=socket(AF_INET,SOCK_DGRAM,0);
    bzero(&servaddr,sizeof(servaddr));
    servaddr.sin_family = AF_INET;
    servaddr.sin_addr.s_addr=inet_addr(addr);
    servaddr.sin_port=htons(5527);

    sendto(sockfd,sendline,strlen(sendline),0,
               (struct sockaddr *)&servaddr,sizeof(servaddr));

    // Create CFSocket
    const CFSocketContext   context = { 0, (__bridge void *) (self), NULL, NULL, NULL };
    CFSocketRef _cfSocket;
    _cfSocket = CFSocketCreateWithNative(NULL, sockfd, kCFSocketReadCallBack, kCFSocketReadCallBack, &context);

}

Hi,

I am new to objective c. As a part of a simple project I needed to build a UDP based client in objective c.

I have managed to create C based socket and get a CFSocket reference from it.

The place where I am stuck is:

Get a CFReadStreamRef and CFWriteStreamRef for the CFSocket that I have created.

is there a way that I can do that? I read the documentation for CFStream at apple but I couldn’t figure out much there. Any suggestions would be great.

Thanks
