exportunfrozen
Use the exportunfrozen statement if unfrozen exports are to appear in the project’s import library.
When it is used, the import library is created as a side-effect of linking so that all exported functions, even unfrozen ones, appear in the import library. This also means that import libraries for compatible ABIs are not created.
If this is not used, you must supply a .def file with the frozen exports.
Use of exportunfrozen is only recommended for the early stages of project development, when the Application Programming Interface is likely to be subject to change.
