Universal thunk

<programming, operating system> A software mechanism allowing a Windows 3.1 application to call a 32-bit {dynamically linked library} (DLL) under Win32s.

The Windows 3.1 application 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-bit EXE loads the 32-bit DLL.
