Causes a data structure to be placed in the .idl file.

[export]

The [export] C++ attribute causes a data structure to be placed in the .idl file and to then be available in the type library in a binary-compatible format that makes it available for use with any language.

You cannot apply the [export] attribute to a class even if the class only has public members (the equivalent of a struct).

If you export an unnamed enum or struct, it is given a name that begins with __unnamedx, where x is a sequential number.

The typedefs valid for export are base types, structs, unions, enums, or type identifiers. See typedef for more information.

The following code shows how to use the [export] attribute:

// cpp_attr_ref_export.cpp
// compile with: /LD
[module(name="MyLibrary")];

[export]
struct MyStruct {
   int i;
};

For more information, see Attribute Contexts.
