We have a bit of a dilemma here, but we have an idea.
In an effort to simplify our lock system, we will instead use a combination of locks and signals.
For example, let’s say we have a list of objects and a lock object.
Let’s call the lock object A, and the signal object S. Now, if we want to create a lock on an object, we first create a new lock object, and then modify its lock state.
Then, we have the following code: Locks, semaphored signals, lock objects: This code is very similar to our locks example above.
However, in this case, we are actually creating a signal for the lock to receive, and it’s going to do its job by signaling the lock, and letting it know when the lock is ready to receive a lock.
This signals are going to act as a bit mask to tell the lock what to do when the signal arrives.
Finally, if the lock returns, the lock will then perform some action that is necessary to make sure the lock doesn’t become locked by another signal, such as changing the locks state or removing the lock.
So, when a lock is created, the signal will act like a bitmask and let the lock know what to make of it.
If the lock was created by a user, it will know that the lock should be locked by that user, and not by some third party.
So in a way, we can use signals to make the lock system more efficient, but at the same time, they can also create a lot of unnecessary complexity.
So let’s move on to the next part of our lesson.
