Reference Nullification

Definition

Invalidating all pointers that reference a specific memory block, ensuring that the block cannot be accessed or modified after deallocation.

How it Works

Nullifying references to memory blocks makes those blocks no longer accessible. This is critical to prevent use-after-free errors.

Considerations

If a memory block is freed, all other references to that block should be nullified.

This is particularly relevant when manually managing memory.
