Hazard pointer

A hazard pointer is a special kind of pointer used to help computer programs run safely and efficiently, without causing any harm or damage to the computer. It works like this: when a computer program is running, it often needs to modify or read from memory, which is the place where data is stored and accessed. The computer is constantly changing and updating information, and this makes it easy for data to get corrupted, or for something to go wrong. A hazard pointer is a special type of pointer that helps protect the data that is being read or modified, by setting aside a "safe area" in memory that is not used by any other part of the program. So, if something goes wrong while the program is modifying or reading the data, the hazard pointer will make sure it is safe and not corrupted. This helps protect the computer from harm while the program is running.
