typedef struct <-> struct

[Konrad Windszus]

What's the difference between typedef struct _MYSTRUCT { int nValue; DWORD dwValue2; }MYSTRUCT; and struct MYSTRUCT { int nValue; DWORD dwValue2; }; With each of them I can instantiate variables of type MYSTRUCT like: MYSTRUCT myStruct; And I doesn't need the old C style: struct MYSTRUCT myStruct; So why should I use typedef combined with struct. Are there any advantages or disadvantages. Thanks for any comment. Konrad

you're not obiged to... the reason some code use this, it is because C don't allow to use types without the struct identifier, or when your struct is typedefed... In C++, it is only a portability reason...

In a good old C, you can use structures only with the keyword struct. In C++, the only advantage of using typedef is, that you write the struct name with one word :). In your example, MYSTRUCT is an alias to struct _MYSTRUCT. Robert-Antonio "Czech Railways discovered, that in case of disaster the most damaged wagons were the first and the last. So they decided to create trains without them."
