How i can use shared memory in workerman?

Hi. Any suggestions about how i can organize shared memory between worker processes in workerman? What classes\abstractions should i use? Any analogue for std::mutex or std::lock_guard c++ mechanics?

I need to keep piece of data between workerman processes and write\read to it. Am i correct saying that this is not implemented?

As long as i understood each callback for onMessage, onConnect, e.t.c can and will be called in different worker sub process thus providing parallelism, this is correct?

No files, tests, or entry points are named. Start by reviewing Workerman’s worker-process model and any existing mechanisms for sharing state or synchronizing access, then verify how callbacks are dispatched across workers. Done would be a documented, supported approach or a clear statement of the limitation.
