Disconnecting from server

[tawanda diza]

Hie Team.

I am having this problem:
I am developing an application that is connecting to a server, the problem is when the server is not responding, the application wont allow me to do anything so i end up restarting the machine,

i am receiving data using the receive function as follows

nData = recv( hServer, &wzRec[iPos], nLeft, 0 );

please help

thanks in advance

I search on google about your problem.

I got one commmon solution it says using select() function before using receive

another solution i got a forum is more interesting

   { /* this block is just after the return from the socket() call and before connect() */
            struct timeval tv; /* timeval and timeout stuff added by davekw7x */
            int timeouts = 0;
            tv.tv_sec = 3;
            tv.tv_usec = 0;
            if (setsockopt(sockfd, SOL_SOCKET, SO_RCVTIMEO, (char *)&tv,  sizeof tv))
            {
              perror("setsockopt");
              return -1;
            }

            if (connect(sockfd, (struct sockaddr *)&their_addr, sizeof their_addr) == -1) {
                perror("connect");
                exit(1);
            }

            while (((numbytes=recv(sockfd, buf, MAXDATASIZE-1, 0)) == -1) && (++timeouts < 1000)) { /* loop to retry in case it timed out; added by davekw7x */
                perror("recv");
                printf("After timeout #%d, trying again:\n", timeouts);
            }
            printf("numbytes = %d\n", numbytes);

            buf[numbytes] = '\0';

            printf("Received: %s",buf);
        }

hie johny

do yu have any idea on how to use this code for that problem above

struct timeval tv;

  tv.tv_sec = 3;  // 1 Secs Timeout 

  setsockopt(hServer, SOL_SOCKET, SO_RCVTIMEO,(char*)&tv,sizeof(struct timeval));

I would be very grateful if you would tel me where exactly to put the code like what you told me in your first reply

I am having problems with your first code its not doing any thing at the moment.
THANKS
