What I would like to have is a <type>.offsetof(<datamember>) property for struct
or union types. In C/C++ the preprocessor is used for this purpose, for example
(from windows):

#define FIELD_OFFSET(type, field)    ((ulong)(ulong*)&(((type *)0)->field))

Is there currently a way to do this in D?

Dan

Good idea. Maybe it can be done in an OO way as a static property:

<struct>.<member>.offset

Yes; tag.member.offset should do it. -Walter
