Using Visual Studio 2003/2005 I create a project of type Visual C++
Class Library (.NET).

I add a method. In this method I need to open a file and write to it. I
type:

fopen("out.lis", "wt");

I get fopen identifier not found. I add #include <stdio.h> I get:

unresolved external symbol "struct_iobuf* _cdecl(char const*, char
const*)

Can anyne help me here?

Thanks.
