SWI-Prolog -- Summary of files

The following files are provided:

SWI-cpp2.h - Include this file to get the C++ API. It automatically includes SWI-cpp2-plx.h and SWI-cpp2.cpp, unless the macro _SWI_CPP2_CPP_SEPARATE is defined, in which case you must compile SWI-cpp2.cpp separately.
SWI-cpp2.cpp - Contains the implementations of some methods and functions. If you wish to compile this separately, you must define the macro _SWI_CPP2_CPP_SEPARATE before your include for SWI-cpp2.h.
SWI-cpp2-plx.h - Contains the wrapper functions for the most of the functions in SWI-Prolog.h. This file is not intended to be used by itself, but is #included by SWI-cpp2.h.
SWI-cpp2-atommap.h - Contains a utility class for mapping atom-to-atom or atom-to-term, which is useful for naming long-lived blobs instead of having to pass them around as arguments.
test_cpp.cpp, test_cpp.pl - Contains various tests, including some longer sequences of code that can help in understanding how the C++ API is intended to be used. In addition, there are test_ffi.cpp, test_ffi.pl, which often have the same tests written in C, without the C++ API.
