writebyte() implementation

[Grimlen]

I'm attempting to write a: writebyte() function in which the client
specified to write a byte of data to the server, and the server will read this data as a byte

Here's my writebyte():

void writebyte(sf::UdpSocket *socket, unsigned char b){
        if (socket->send(&b, sizeof(b), "127.0.0.1", 4567) != sf::Socket::Done){
                //Error
                cout << "message was not sent" << endl;
        }
}
 

And my readbyte():

unsigned char readbyte(UdpSocket *socket){
        unsigned char byte;
        std::size_t received;
        sf::IpAddress sender;
        unsigned short port;

        int rec = socket->receive(&byte, sizeof(byte), received, sender, port);
        if(rec != sf::Socket::Done){
                //Error
        }
        if(rec == sf::Socket::Disconnected)
                cout << "D/C" << endl;
        return byte;
}
 

I've so far gotten a few functions to work:
writeint()
writefloat() and
writeshort()

The server receives the data correctly.
However for writebyte() and readbyte(), the data is not read correctly.
For example, I've sent the following data using writebyte():

                                unsigned char c = 253;
                                writebyte(&socket, c);
 

Here's what the server writes:


Any idea what's wrong?

An [unsigned] char is written in the console as a character. You need to cast it to an int to see its value.

Thanks got it!
