These DLLs provide access to almost all of Clipper2's features via the functions exported in clipper.export.h. This file also documents the simple (language agnostic) data structures required by these functions.

The repository's DLL folder contains not only the Visual Studio project files used to compile these DLLs, but also source code for a Delphi utility which demonstrates using these DLLs.
