typedef struct foo{} foo

[JonLT]

Hi!
I was just wondering what this means (in c++):
[code=cpp]
typedef struct foo{} foo;
[/code]
is it some way of prototyping a function as a struct, or an array as a struct or something?
I found it in a header im using, with it im using a .lib and a .dll, so i don't known what whats really going on, but i'd like to know what the above means.
Thanks.

is it maybe the same as a class prototype?
[code=cpp]
class foo;
[/code]

It simply defines another name 'foo' for an empty struct which, incidentally, has
the same name 'foo] as its struct tag but that's irrelevant.

kind regards,
