Exporting a C Class from a DLL: Late-Binding Considerations

When exporting functions from a DLL, the __declspec(dllexport) directive is commonly used. But how do we export and dynamically load entire C classes?

Late-Binding via LoadLibrary()

Directly loading a class using LoadLibrary() is typically not possible. Instead, two approaches are available for dynamically linking to a class:

Approach 1: Factory Function and Assembler

Create a factory function to instantiate objects and use assembler to link them to the DLL's offsets after loading the DLL dynamically. This approach is explained in detail here: [Dynamically loading C objects from DLLs](https://www.codeproject.com/Articles/18878/Dynamically-loading-objects-from-DLLs).

Approach 2: Delay-Load DLL

Utilize a delay-load DLL, which allows dynamic loading of a DLL and its exports at runtime. However, this method may not be available on all platforms.

Compile-Time Linking with Header and Lib

For compile-time linking, you can either:

• Let the linker handle it by including the exported class symbol and linking with the appropriate import library.
• Use preprocessor macros to explicitly control export behavior. This is commonly used when creating DLLs with exported symbols. Visual Studio automatically generates these macros when creating DLLs with the "export symbols" option enabled.
