Hi
I'm trying to implement a client/server protocol buffer stream.
When using tcp/ip the issue is to know where a message end and a new message begin.
The solution is to implement length-prefix messaging system.
Is there a way to send message-length + message at the same time through a socket??
Any code snippets would be appreciated ^^
thx in advance.

Solution 1

Just add the message length to the beginning of your message as an integer value (don't forget to convert it via htonl()[^]. You could also send this value independently of your actual text and let the receiver re-assemble it when handling the input messages.
