5.4.2 Dynamic Linking based on load_foreign/[2,5]

The predicates below are considered obsolete. They are briefly described here for compatibility purposes. New code should use the predicates from the library(shlib).

load_foreign(+File, +Entry)

Load a foreign file or list of files specified by File. The files are searched for similar to consult/1. Except that the `.o' extension is used rather than `.pl'.

Entry defines the entry point of the resulting executable. The entry point will be called by Prolog to install the foreign predicates.

load_foreign(+File, +Entry, +Options, +Libraries, +Size)

The first two arguments are identical to those of load_foreign/2. Options is (a list of) additional option to be given to the loader. The options are inserted just before the files. Libraries is (a list of) libraries to be passed to the loader. They are inserted just after the files. If Size is specified Prolog first assumes that the resulting executable will fit in Size bytes and do the loading in one pass.

foreign_file(?File)

Is true if File is the absolute path name of a file loaded as foreign file.
