Question

For some reason I keep getting

error C3861: '__typeof': identifier not found

when I compile my program!

I’m including the following libraries:

<iostream>
<stdlib>
<stdio>

Any ideas?

thanks

Edit:

More example

User.h
class User{}

main.cpp
void f(User* p)
{
.
.
.
__typeof(p) ...
.
.
.
.
}

__typeof only exists for /clr:oldSyntax. Are you trying to use Managed extensions to C++ or are you expecting __typeof to work like C++0x’s decltype? If so, if you are using VS 2010 you can use decltype.
