use a std:map, and a mutex over all map operation
Only understandable way to do this. But has some constraints. My assumptions won't consider that using a mutex is necessary unless your application allows asynchronous processing + write access for connected devices. If writing process is maintained by your server program, then you know how to do that — Hint: create a condition inside function and don't make it visible in threads, abstract the implementation.
Quote:
use a C array. and assign an ID(0-10239) for each client if connected,If disconnected,the Id would be recycled.
How about you don't use this. Suppose if there are only 10 clients connected, C array will still allocate all of the areas in RAM. Totally not worth it, and as you said — Id would be recycled —, how? What is your algorithm for that?

There are many parts missing in your post, such as, what data will they access, are they going to write data too, to same file or not — mutex and thread-safety makes sense if something is happening on same time at different threads, if not then don't worry about this.
