export
Causes a data structure to be placed in the .idl file.
Syntax
[export]
Remarks
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.
Example
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;
};
