What are race conditions in the pthreads library?

What are race conditions in the pthreads library?

Race conditions occur when multiple threads access shared data simultaneously, leading to unpredictable results.

Can you give me an example of a race condition?

Sure! If two threads increment the same counter variable without synchronization, they might read the same value and both increment it, causing a loss of updates.

How can I prevent race conditions in my code?

You can use mutexes or other synchronization mechanisms to ensure that only one thread accesses the shared data at a time.

What are mutexes and how do they work?

Mutexes are mutual exclusion locks that allow only one thread to access a resource at a time, preventing race conditions.
