public class DllVersionInfo
extends com.jniwrapper.Structure

This class represents the DLLVERSIONINFO structure and provides the ability to load this structure from a specified library.

Note: Not all libraries have the DllGetVersion function, which is used by this class. Therefore, loading of version information from such a library will fail with NoSuchFunctionException thrown.

Field Summary
