  • Thanks Josh, offset value from where to where. – daniel benisti Oct 14 '20 at 13:17
  • To my experience, _off indicates a 32-bit pointer (in x32 world), thus being rather misleading in case you except some address offset. The _off name might have its origin in the segmented addressing introduced by Intel many years ago in their 16-bit times (segment:offset), today being rather obsolete because of the flat memory model also being used in the Intel world. BTW, just discovered that your question is a duplicate of this one stackoverflow.com/questions/50908226/…, offering a more detailed explanation. – josh Oct 14 '20 at 14:21
