New in R3B: a second method to
send events from an extension library to Trinc-PrologProlog clauses and Trinc-Prolog classes can be implemented in so called extension libraries, these extension libraries are Windows DLL (Dynamic Link Libraries) files. It is possible to extend Trinc-Prolog with your own built-in predicates written in C/C++ or any other language, programming tool, which can create Windows DLL's.
Predicates and classes implemented in an extension library are declared as external, if Trinc-Prolog detects that an external predicate is being used it automatically calls a function with the same name in the associated library. There is no difference between calling 'normal' built-in predicates like put_char/1 and external predicates.
Extension libraries can be installed in two different folders, it is possible to install them in a subfolder called plugin of the executable using the libraries or in the same folder as the executable. With the predicate load_external_library/1 it is possible to load an extension library that is located at a different position.
