What is thread safety in the pthreads library?

What is thread safety in the pthreads library?

Thread safety in the pthreads library refers to the ability of multiple threads to access shared data without causing data corruption or inconsistencies.

How can I ensure thread safety when using pthreads?

You can ensure thread safety by using mutexes, condition variables, and other synchronization mechanisms provided by the pthreads library.

Can you give an example of using a mutex?

Sure! Here's a simple example: you can use pthread_mutex_lock() to lock a mutex before accessing shared data and pthread_mutex_unlock() to unlock it after you're done.

What happens if I forget to unlock a mutex?

If you forget to unlock a mutex, it can lead to deadlocks, where threads are waiting indefinitely for the mutex to be released.
