ABOUT
~~~~~

    These are some simple programs that demonstrate how to program
    using SDL_net.


COMPILATION
~~~~~~~~~~~

    run "make"

THE PROGRAMS
~~~~~~~~~~~~

dnr.c
    demonstrates:
        Host Name and IP lookup, and initialization of the IPaddress struct
        SDLNet_ResolveHost
        SDLNet_ResolveIP

    try:
        ./dnr 24.8.116.27
        ./dnr jonatkins.org

tcpserver.c
    demonstrates:
        A TCP message server
        SDLNet_ResolveHost (for a server)
        SDLNet_TCP_Open
        SDLNet_TCP_Accept
        SDLNet_TCP_GetPeerAddress
        SDLNet_TCP_Recv
        SDLNet_TCP_Close

    try:
        ./tcpserver 9999

    usage:
        Run as above...
        Then run tcpclient as shown below.
        The tcpclient entered string should show up here when received.
        This server will accept multiple sucessive connections, until it quits.

tcpclient.c
    demonstrates:
        A TCP client for tcpserver
        SDLNet_ResolveHost (for a client)
        SDLNet_TCP_Open
        SDLNet_TCP_Send
        SDLNet_TCP_Close
    
    try:
        ./tcpclient localhost 9999

    usage:  
        Enter a string, or Q to make the tcpserver quit.
        You may call this from another host using the servers hostname
            instead of localhost.
        This should be able to be called multiple times until you make
            the server quit.

tcpmultiserver.c
    demonstrates:
        A TCP chat server that allows multiple clients to connect
            This is actually a feature full server, supporting some /commands
        SDLNet_SocketSet (all functions, except SDLNet_DelSocket's)
    
    try:
        ./tcpmultiserver 9999
    
    usage:
        Run as above...
        Then run tcpmulticlient as shown below.
        The tcpclient entered string should show up here when received.
        The client's strings should also be forwarded to all connected clients.
        Joins and disconnects will be reported to all clients,
            as well as on the server.
        This server will accept multiple connections in parallel,
            until it is killed.

tcpmulticlient.c
    demonstrates:
        A TCP client for the tcpmultiserver
            Also a suitable system for text input while reading a socket.
        SDLNet_SocketSet (just for one socket)
        select (for keyboard input)

    try:
        ./tcpmulticlient localhost 9999 Klonkus
        ./tcpmulticlient localhost 9999 Frumpy

    usage:
        Run the tcpmultiserver as shown above...
        Then run both the above command lines.
        You should see both clients connect to the server.
        Now you can enter messages in each window (press enter)
        The messages will be distributed to the server,
            and then back to the clients.
        Type /help for the commands the server supports...
        Type /quit and an optional message to quit
        Press Control-C (or EOF[Control-D] if you want) to quit harder

tcpmulticlientthreaded.c
    demonstrates:
        same as tcpmulticlient.c
        plus: SDL_Threads are used for all I/O

    try:
    usage:
        (See the tcpmulticlient.c stuff above!)

tcptimesync.c
    demonstrates:
        simple TCP reading and writing
        time syncronization in 5 packets

    try:
        ./tcptimesync 0 7777 &
        ./tcptimesync 500 7777 localhost

    usage:
        tcptimesync lag port [hostname]
            if hostname is not given, the server is started
            lag is the desired simulated lag time in milliseconds
            the lag argument is ignored in server mode
        run the first line above to start the server
        run the second line above to connect and do a time syncronization
        it should settle on a lag close to 500
        but the important thing is that the client time is close to the 
            time the server has...and this is hard to show across the internet.
        (note: more info will be provided on this if you prod me :)

tcptimesyncserver.c
    demonstrates:
        a seemingly more flexible implementation of tcptimesync.c's server half
        it also loops until the server decides that the client is in sync enough
    
    try:
        ./tcptimesyncserver 7777
        (in separate terminal run tcptimesyncclient as shown below)

    usage:
        tcptimesyncserver port [minoff]
            port is the server port number
            minoff is the minimum allowed millisecond error before sync is
                decided to be achieved
        run the client below as many times as you want
        only one client can be synced at any one time
        the server only dies on control-C (or kill)
    
tcptimesyncclient.c
    demonstrates:
        the client side of tcptimesyncserver
    
    try:
        ./tcptimesyncclient localhost 7777 100
    
    usage:
        tcptimesyncclient hostname port [lag]
            hostname and port of a running tcptimesyncserver
            lag is milliseconds of simulated lag desired (1000 = 1 second)
        run the server above then you can run this however many times you like.

udptftpserver.c
    demonstrates:
        an advanced UDP demo
        UDP (and only UDP) file transfer server
        server for udptftpclient
        does not use SDLNet_SocketSet
    
    try:
        ./udptftpserver 7777 6000

    usage:
        udptftpserver port [packet-length]
            port is the server port number
            packet-length is the size of each packet sent for the file transfer
                it must be greater than 6 to work at all...
                I dunno that max size...but 65535 is too big! (it seems)
        this is an insecure server,
            adding security would be an exercise for you.
        this server can only handle one transfer at a time,
            make it do more yourself.
        use with udptftpclient as shown below...

udptftpclient.c
    demonstrates:
        an advanced UDP demo
        UDP (and only UDP) file transfer client
        client for udptftpserver
        does not use SDLNet_SocketSet
    
    try:
        ./udptftpclient localhost 7777 /bin/sh
    
    usage:
        udptftpclient hostname port filename
            hostname and port of a running udptftpserver
            filename is a file available to udptftpserver to read
        this is an insecure client, adding security would be an
            exercise for you.
        filename may have an absolute path to access anything on the
            server's filesystem.
        I achieved a rate of 3.13 MB/s on my 100base local network...
            (1472 bytes/packet udptftpserver)
        I achieved a rate of 4.80 MB/s on local loopback.
            (1797 bytes/packet udptftpserver)
        So I arrived at a safe 1400 bytes/packet in the program.
        A better server may dynamically send more or less packets per group
            to help the network not be overloaded.
        I have transfered files up to almost 192MB in size.
        it could be tweaked along with the server for more performance.
