How do thread priorities work in the pthreads library?

In the pthreads library, thread priorities determine the order in which threads are scheduled for execution. Higher priority threads are given preference over lower priority ones.

Can I set different priorities for different threads?

Yes, you can set different priorities for threads using the pthread_setschedparam function, which allows you to specify the scheduling policy and priority.

What happens if two threads have the same priority?

If two threads have the same priority, the scheduler will typically use a round-robin approach to allocate CPU time between them.

Are there any limitations to using thread priorities?

Yes, the effectiveness of thread priorities can depend on the underlying operating system's scheduling policies and may not always guarantee the expected behavior.
