The integer type is 32-bit and has 4 bytes. Now we need to be able to extract one of its 32-bit values. But the smallest integer type of Delphi is also a byte (8 bits): byte (unsigned), struct int (Signed ). Otherwise, start with extracting a byte:

I collected a list of common questions: 1. How to judge whether a single-chain table has a ring 2. How to determine the entry point of a ring 3. How to know the ring Length 4. How do I know whether two single-chain tables (with no rings) overlap? 5.
