Code Explanation:
At the heart of the code, we have a couple of classes: RealTimeQueue and RealTimeScheduler. Both of these are geared towards making our system function effectively in a real-time context.
The RealTimeQueue class serves as a thread-safe messaging queue, perfect for real-time systems where data integrity and timely processing are crucial. A mutex lock provides mutual exclusion, ensuring that only one thread can access the buffer at once. Additionally, with a condition_variable, we prevent busy-waiting, making it more efficient and responsive.
Now, for the brawn of our system: RealTimeScheduler. This oneās a real gem, ācause it allows us to schedule tasks at a fixed interval, simulating a real-time environment. The scheduler keeps track of tasksāfunctions to be executed periodically. And hoo-boy, isnāt that run method just a thing of beauty? A precise timing loop guarantees that tasks are ticked every 10 milliseconds.
The main event, ladies and gents, is where we orchestrate our symphony of tasks. We add two lambdas to our scheduler: one pumping out integers to our queue, and the other consuming them like thereās no tomorrow. When the curtain risesāor in our case, when scheduler.start() is calledāour tasks get going in their never-ending dance of production and consumption.
A gentle 1-second nap lets the scheduler put on quite the show, thenāwith a heavy heartāwe call scheduler.stop() to bring the curtain down on our real-time performance.
There you have it: a meticulous tour of a system that eats real-time for breakfast. Slap this into any high-stakes scenario where timing is everything, and youāll see this code shine brighter than a diamond-backed function pointer.
