5.2.1 What linking is provided?

The static linking schema can be used on all versions of SWI-Prolog. The feature/2 predicate may be used to find out what other linking methods are provided for this version.

• feature(open_shared_object, true)
  If this succeeds the system provides the open_shared_object/2 and related predicates that allow for handling Unix shared object files based on the Unix library functions dlopen(2) and friends. See section 5.4.
• feature(dll, true)
  If this succeeds the system provides an interface for loading .DLL files by means of open_dll/2 and friends. See section 5.4.

If either the feature open_shared_object or dll is true, the library library(shlib) provides a common interface for loading foreign files from Prolog.
