VFP does not produce a C-style .DLL; instead, it creates an in-process COM server, accessed via OLE Automation. You would access the .DLL by creating and instantiating an in-process server by the equivalent of CREATOBJECT() or NEWOBJECT(); functions would be method invocations. See Chapter 16 (Adding OLE) of the VFP Programmer's Reference for details. This is accessible in the on-line documentation.
