Sending and receiving "File" over a socket
Really need to send or receive "File" in the socket. Since it is implemented in the "Connection"
PHP Code:
Bool dataFull (File fInt sizeBool send true);

RE: Sending and receiving "File" over a socket
you can do it manually, using Memc<Byte>, File::put, get

I recommend that you use Connection (TCP/IP) or FastConnection (UDP) which have File based methods

RE: Sending and receiving "File" over a socket
Thanks I will try to use "FastConnection" . I have long been using "Connection" to connections of the client / server. But I need to transfer data between the clients client/client. I do it for unloading the server and wanted to implement it through sockets.

FastConnection only takes a sequence of values ​​of type "Byte"
Code:
Int receive(SockAddr &addr, Byte (&data)[65536]);
How to do it would take "Str" and "Byte or Int" simultaneously ?.How it is implemented in "Connection".

File::readMem, look into headers more carefully

Thank you. It's bad for me -> "order of received data is not guaranteed to be the same as when sending". How to use the Connection at the same time to communicate with the server and exchange between clients?

I use the "Connection" to connect a client / server - it works perfectly !.But how can I use this class to be used between clients if it is set once Bool clientConnectToServer(C SockAddr &server_addr); ?


I need some frequently transmit the position of some items, status of players in the "playroom" and other not very important data. I do not want to send them through the server to other players. I want to exchange the data between clients. It will not load the server. For example: WorldOfTanks on a single server supports 200 000 (200k!) players online

Over TCP/IP (Connection) the received data order IS guaranteed.
Just put that byte array you received into a File object

Code:
File filebuffer; // SIZE is 1024.
filebuffer.writeMem();

Byte buffer[1024];

Int count = socket.receive(buffer, SIZE(buffer));
for (int i = 0; i < count; i++)    filebuffer << buffer[i];

And there you have your data in the file as you received it.
Im not sure if that code works, I just arranged a little piece of mine's... Im not using Connection, but Socket, with a custom NetMgr class...

Also in TCP consider that if you send 2 pkts at the same time.. if they are small enought they will be merged into one.
