What exactly is meant by recursive lock, and is it bad, and if so why?

Also, does the POSIX standard support recursive lock via
pthread_mutex_lock?

In another thread, someone stated that a code requirement was bad
because it required recursive lock, so I'm trying to understand his/her
position.

I believe recursive lock means you can call the lock multiple times
from the same thread and it won't block your thread.
I'm not sure if it means you need to call unlock the same amount of
times you called lock.
