A software mechanism allowing a Windows 3.1application to call a 32-bit {dynamically linked library} (DLL) under {Win32s}.The Windows 3.1application which wants to call an entry in a 32-bit DLL instead calls a corresponding entry in a 16-bit DLL.The programmer must also include code to detect whether the 32-bit DLL is loaded.A 32-bitEXE loads the 32-bit DLL.See also Generic Thunk, Flat Thunk.["Calling a Win32 DLL from a Windows 3.1 Application", Win32 SDK Knowledge Base, Article ID Q97785].[Better explanation?](1997-10-11)
