What are some common errors when using semaphores in programming?
Some common errors include forgetting to release a semaphore, deadlocks, and using the wrong semaphore type.
Can you explain what a deadlock is?
A deadlock occurs when two or more processes are waiting for each other to release resources, causing them to be stuck.
How can I avoid deadlocks when using semaphores?
To avoid deadlocks, ensure that all processes acquire semaphores in a consistent order and use timeouts.
What is the difference between binary and counting semaphores?
Binary semaphores can only be 0 or 1, while counting semaphores can take on a range of values, allowing multiple accesses.
