9.2.1 What linking is provided?

The static linking schema can be used on all versions of SWI-Prolog. Whether or not dynamic linking is supported can be deduced from the Prolog flag open_shared_object (see current_prolog_flag/2). If this Prolog flag yields true, open_shared_object/2 and related predicates are defined. See section 9.2.3 for a suitable high-level interface to these predicates.
