Hello!
Today I wanted to transfer a 6kb file from one server to the game server over a TCP connection.
As far as I know, the maximum packet size is 65535 bytes. This is more than enough to transfer this small file in one package.
I noticed that I am sending a complete packet, and socket splits it into parts by calling the receive function several times.
I read about SocketSetOption but I don't understand how to use it correctly because it leads nowhere.
Please tell me how you can disable the division of the package into parts!
I hope for your answer. Thanks in advance!

TCP packets are typically no larger than 1500 bytes before they're fragmented, but you can try to set the MSS like this:

PHP Code:

SocketSetOption(socket, SocketSendBuffer, 6144); 


I'm not sure how the packet will be received since devices may expect <=1500 MTU. Maybe someone who knows more about this subject can chime in.

TCP is a streaming protocol, the application protocol and receiving end need to deal with any size fragments and reconstructing the sent data (due to naggle you can even have multiple writes sent as a single packet).

Thanks to Kolapsicle and asherkin for the answer. I realized what I needed to do.
