The offsetof Macro
------------------

The offsetof macro (defined in STDDEF.H) takes a struct type name and
member name, and returns a type size_t value giving the offset in
bytes of the member from the beginning of the struct.

The expression

   offsetof( type, member_name )

yields the byte offset of the member from the beginning of the struct.
