[RESOLVED] Getting the length of a string of a buffer

[steve_rm]

Hello,

I have a buffer that contains words. However, the words comes from a client. I just want to get the words out. However, the buffer is being filled with rubbish after the words. Example "Manchester United&^&*#&#&##^&#@*&^^ etc.

How can I just get "Manchester United" out?

I have used the following using length and substring, but it displays everything

char buffer[256];		
		sock.receiveFrom(buffer,sizeof(buffer), addr);
		std::string message = buffer;
		int strLength = 0;
		strLength = message.size();
		std::cout << "The length of the string is: " << strLength << std::endl;
		message = message.substr(0,strLength);
		std::cout << message;

Many thanks,

Steve

Is it resolved?

If so, what did you do to resolve it? It might help someone else with a similiar problem.

If it's not resolved, it's up to the client to indicate the end of string. If it doesn't, there's no way a program can figure out where the end is on the fly.
