Structures

Question 1

memory allocation

Answer 1

In addition to aligning the fields of a record at reasonable offset
boundaries, most compilers will also ensure that the length of the entire
record is a multiple of two, four, or eight bytes. They accomplish this by
adding padding bytes at the end of the record to fill out the record’s size.

Question 2

Manual memory padding

Answer 2

type
aRecord: packed record
bField :byte;
padding0 :array[0..2] of byte; (* add padding to dword align wField *)
wField :word;
padding1 :word;
(* add padding to dword align dField *)
dField :dword;
end;
