Thread: Why does server receive wrong message from client?

Why can't you post code properly? It's not difficult. Just make sure you post it as plain text.

And the whole "errnoOut" thing seems pointless to me. What's wrong with:

Code:

int sendIPv6J(int sockfd, char buffer[]) {
    return send(sockfd, buffer, strlen(buffer) + 1, 0);
}
// ...
    strcpy(Cbuffer, "Client says hello server!!!");
    n = sendIPv6J(Csockfd, Cbuffer);
    if (n < 0) {
        perror("sendIPv6J");
        exit(EXIT_FAILURE); // or whatever
    } else {
        printf("Client: SENT MSG : %s : of size %d\n",
               Cbuffer, n);
    }

(Notice how the code looks better when posted properly?)
