I don't understand why you need this with a nonzero timeout in select()...
printf("datatoread: %i\n",datatoread);
}
while(!datatoread);
asock = accept (server_socket, (struct sockaddr *) &asock_in, &ddrlen);
err = send (asock, &send_buff[0], strlen (send_buff), 0); if(err != strlen (send_buff)) printf("Error sending to socket\n");
It is not an error for err to be < strlen (send_buff), as long as it is > 0. == 0 is in many cases not an error either, I think.
My guess is your problem comes from socket() or bind() failing. Check their return value, and errno.
Thanks, Bas
Hi,
I checked for errors, the socket is created and binded correctly. I also forgot to say that increasing the timeout the select works well, but using a short timeout like in the example, it doesn't report any data.
