What are some common mistakes when using condition variables and semaphores?
Some common mistakes include forgetting to signal condition variables, using them without proper locking, and deadlocks.
Can you explain why forgetting to signal condition variables is a problem?
Forgetting to signal can lead to threads waiting indefinitely, causing your program to hang or behave unexpectedly.
What about using semaphores incorrectly?
Using semaphores incorrectly can lead to race conditions or deadlocks, especially if the counting is not managed properly.
How can I avoid these mistakes?
To avoid these mistakes, always ensure proper locking, signal condition variables after changes, and carefully manage semaphore counts.
