stack smashing deteced

[lilac socket]

Hi guys i have a programm which receives 1 byte at a time from a server and writes it in a buffer and then prints it
but somewhow i get this stack smashing detected

Buffersize is 1

    int total_bytes = 0;
    int bytes_received = 0;

    while (1) {
        bytes_received = recv(socket_descriptor, buffer + total_bytes, BUFFFER, 0);

        if (bytes_received <= 0) {
            // Handle error or connection closure
            break;
        }

        if (buffer[total_bytes] == '\n') {
            buffer[total_bytes + 1] = '\0';
            break;
        }
        total_bytes++;
    }


    printf ("Nachricht erhalten: %s\n", buffer);

pay careful attention to where you're telling recv to start writing, how you're handling null termination, and how much you're writing to the buffer

oh tanks mate

another question

    send(socket_descriptor, "VERSION 2.4\n", sizeof("VERSION 2.4"), 0);

    readFromServer(socket_descriptor, buffer);

    printf("Nachricht erhalten: %s\n", buffer);

    send(socket_descriptor, "ID 33uwj28t4xtv2\n", sizeof("ID 33uwj28t4xtv2"), 0);

it works

but my problem is

i send this string : VERSION 2.4\n

but size i specify toss end is : VERSION 2.4

isnt that 1 byte less?
