What is pthreads_join and how does it work?

Can you explain what pthreads_join does in multithreading?

Sure! pthreads_join is a function used to wait for a specific thread to finish its execution.

How do I use pthreads_join in my code?

You would typically call pthread_join(thread_id, NULL); where thread_id is the ID of the thread you want to join.

What happens if I don't use pthreads_join?

If you don't use pthread_join, the main thread may terminate before the other threads finish, leading to resource leaks.

Are there any alternatives to pthreads_join?

Yes, you can use pthread_detach if you don't need to wait for the thread to finish, allowing it to run independently.
