Storing client addresses

kulesz · 09-19-2011 08:41 PM

If I store clients similar to ConnectionServer - in a map (or vector), with their socket addresses (SockAddr) as a key, how can I validate, if the client is still connected?

For example, addresses of clients that are standing in a specific area are pushed into a vector. After some time, I'd like to iterate through this vector and do some action on clients. However, some of the clients may have already disconnected - how can I verify this?

Eventually, what is the best way to store clients information with ability to verify it's correctness?

You can try to send a ping to each client, and if they don't reply in x time you could assume that they are disconnected.

ConnectionServer class will automatically remove the elements (clients) upon disconnection

OK, so I'm storing part of my clients (that did specific action in game) in Memc<SockAddr> container. After some time, I want to iterate through this container and send some messages to all those clients. But some of them may have already disconnected and I still have their socket addresses in memory. How can I check, during iteration, if the client still exists (and it's still the same client)?

And one more problem - why doing:

Code:

void RemoveChunk(const SockAddr address, UInt x, UInt z)

{

   chunks[x][z]->clients.exclude(address);

}

gives me:

clients is the Memc<SockAddr> container.

Heh, nothing came on my mind when I was trying to think of some title for the project :-P
Well, I tried without const and it's still the same :-/

Still... Doing:

if (clients.has(client->connection.address())) {};

But clients.add(client->connection.address()) works OK.

**Esenthel** · 09-23-2011 07:30 PM

comparators for SockAddr don't take const parameter,
I'll try to improve it for next sdk

btw: you can use Client destructor call information to get the time of removing the client from client list
