What are the common challenges faced when using semaphores in programming?
Some common challenges include deadlocks, priority inversion, and complexity in managing multiple semaphores.
Can you explain what a deadlock is in this context?
A deadlock occurs when two or more processes are waiting indefinitely for resources held by each other, causing a standstill.
How can I prevent deadlocks when using semaphores?
You can prevent deadlocks by ensuring a strict order of resource acquisition, using timeouts, or employing deadlock detection algorithms.
What is priority inversion and how does it relate to semaphores?
Priority inversion happens when a lower-priority task holds a semaphore needed by a higher-priority task, causing delays.
