What are some common semaphore errors in C++?

Common semaphore errors in C++ include deadlocks, improper initialization, and race conditions. Would you like to know more about any specific error?

Can you explain what a deadlock is?

A deadlock occurs when two or more threads are waiting for each other to release resources, causing them to be stuck indefinitely.

How can I avoid deadlocks when using semaphores?

To avoid deadlocks, ensure that all threads acquire semaphores in a consistent order and use timeouts when waiting for resources.

What about race conditions?

Race conditions happen when multiple threads access shared data simultaneously, leading to unpredictable results. Using semaphores correctly can help prevent this.
