struct ptr within the same struct

[Ufit]

Compiling the following code (C++):

struct _Item
{
int var1;
.......

_Item *pPointer;


}

under VS6.0 I get no errors but under VS2003 I get error using undefined type.
What is the solution to correctly compile the program using VS2003.
PS VS'06 does the same thing. Please help.
Thanks

Compiling the following code (C++):

struct _Item

The identifier "_Item" is reserved for the implementation. Don't
use it.

{
int var1;
.......

_Item *pPointer;


}

under VS6.0 I get no errors but under VS2003 I get error using
undefined type. What is the solution to correctly compile the program
using VS2003.

I get the syntax error at the line with the dots. When I compile this
program:

struct Item {
int i;
Item* pPointer;
};

int main() {
Item item;
}

with VC++ v7.1 (2003), I get no errors. Read the FAQ 5.8.

I actualy use _xItem - but doesn't matter what name is used - error comes up.
Where's that faq 5.8 ?

The problem is the leading underscore, not the alphanumerics that
follow.

My guess is that you are compiling this as C code, not C++ code. For it to
compile as C code, you need to use struct, i.e.,

struct Item
{
int var1;
struct Item *pPointer;
};
