Sharing heap memory with fork()

Question

I am working on implementing a database server in C that will handle requests from multiple clients. In order to do so I am using fork() to handle connections for individual cli

Answer 1

If you must you fork, the shared memory seems to be the 'only' choice.

Actually, I think in your scene, the thread is more suitable.

If you don't want to be multi-threaded. Here is another choice,you can only use one-process & one-thread mode, like redis

With this mode,you don't need worry about something like lock and if you want to scale, just design a route policy,as route with the hash value of the key
