|
|
* 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.
