Lectures notes for 2010 - KTH

Changed the client
Changing the following:
#define destination_host "127.0.0.1"
#define my_port 52000
server_addr.sin_port=htons(my_port);
Adding some content to the bigBuffer:
sprintf(bigBuffer, "This is a simple test string to be sent to the
other party\n");
Sending only as much of the buffer as necessary:
if ((sendto(client_socket_fd, bigBuffer, strlen(bigBuffer),
sendto_flags, (struct sockaddr*)&server_addr,
sizeof(server_addr))) == -1) {…}
Results in the listener outputting:
Received packet from 127.0.0.1:1260
Data: This is a simple test string to be sent to the other party
String length=59
Maguire Simple UDP client 4: 23 of 74
