Form 1

class _export <class name>

Form 2

return_type _export <function name>

Form 3

data_type _export <data name>


These modifiers are used to export classes, functions, and data.

The linker enters functions flagged with _export or __export into an export table for the module.

Using _export or __export eliminates the need for an EXPORTS section in your module definition file.

Functions that are not modified with _export or __export receive abbreviated prolog and epilog code, resulting in a smaller object file and slightly faster execution.

Note: If you use _export or __export to export a function, that function will be exported by name rather than by ordinal (ordinal is usually more efficient).

If you want to change various attributes from the default, you will need a module definition file.

Note: The __export form is the only one supported by Clang-enhanced C++ compilers.
