The difference between thread-safety and re-entrancy – The Old New Thing

Posted by jpluimers on 2021/01/13

Just in case I need a nice example about the difference: [WayBack] The difference between thread-safety and re-entrancy – The Old New Thing.

It has both that and the definition:

An operation is “thread-safe” if it can be performed from multiple threads safely, even if the calls happen simultaneously on multiple threads.

An operation is re-entrant if it can be performed while the operation is already in progress (perhaps in another context). This is a stronger concept than thread-safety, because the second attempt to perform the operation can even come from within the same thread.
