![]() Here is an example of how registers work when you increment a counter. Why: Think about how registers work in the operating system for a second. When: To help solve concurrency issues when programming with threads. In other words any place where we feel more than one thread will access the data or structure at any given time. Where: We will use semaphores in any place where we may have concurrency issues. What: A synchronization tool used in concurrent programming ![]() The last thing we need to talk about before I explain the problem is semaphores. We have to be very careful in our case that we don’t over fill the buffer or remove something that isn’t there in c this will produce a segmentation fault. Then the consumer will remove the item from the buffer and print it to the screen.Īt this point you may be asking yourself what exactly is a “bound-buffer”? Well a buffer is a container of sorts a bound-buffer is a container with a limit. In our case our producer will produce an item and place it in a bound-buffer for the consumer. ![]() ![]() Let’s talk about a producer-consumer relationship for a second, shall we? Basically, the producer produces goods while the consumer consumes the goods and typically does something with them. SO, today we are talking about the producer-consumer problem, and we are going to solve it utilizing a bounded-buffer and pthreads. ![]()
