How can we use AMXX Plugins to customize the results of Server Queries (If Possible)?

If it is possible, then is there a way to register custom server queries?

Which queries exactly ? A2S ? If A2S_INFO, you can use this (if others use the concept).

[ezio_auditore]

Queries like A2S. Like we register some special query which returns, lets say, the map cycle of the server being.

What do you want to do exactly ? (X-Y Problem warning!)

[ezio_auditore]

Suppose I make a query (A2S_ONE_PLUS_2).

The registered callback on my AMXX plugin fires, does some calculations, and then return me whatever stuff I want.

You could listen to a socket, that's the best possible way to achieve this.

Its better if you tell us what exactly you are trying to achieve. (no XY)

That was the most obvious thing I've said.

I made a plugin which has a function that can calculate the total XP of all players on the server.
Now I want to make a query which gives me this calculated XP...

Most likely possible, but I see no reason why would you want to undergo a lot of hooking engine functions and stuff to change these responses. Probably the best thing you could do is to listen to a socket. Making your own protocol, sort of.
Anyway, you shouldn't do that stuff at AMXX level, but rather at Metamod level.

I tried to make an example of this using UDP sockets but unfortunately there is no way to get the requester IP address (that I know of) without the use of recvfrom() function, which is not built in any of the existing sockets modules. What this means is once your plugin receives the request for info, it doesn't know where to send it to since UDP is connection-less; you need the requester IP/port to send the data back to. If someone is willing to add this to the sockets2 source, I can make it with that. My Visual C++ Express is now erroring on me when I load a project.

You could also form your request packets to include this data in the header, like:
123.23.232.12:port:CommandID

This could all be in binary, so the packet would look like: %^#$#@^$Z

ezio_auditore, what will be requesting data from your server?
