@defgroup swi-c-interface SWI-Prolog Foreign Language Interface
@ingroup fli_c_cx
*
* @tableofcontents
*
* A reimplementation of Jan Wielemaker's SWI-Prolog C-language interface, it supports
* most of the functionality in the original implementation. It allows for:
*
* - Term Construction, Access, and Unification
* - Manipulation of Atoms, Strings, Lists of Codes and Lists of Atoms
* - Query evaluation
* - Thread and Prolog engine management
* - Data-Base Access
*
* In this interface, all Prolog data known by C is referenced through term references (term_t), hence
* Prolog has all the information necessary to perform its memory management without special precautions
* from the C programmer.
