source_file(:Pred,
?File)True if the predicate specified by Pred is owned by file
File, where File is an absolute path name (see
absolute_file_name/2).
Can be used with any instantiation pattern, but the database only
maintains the source file for each predicate. If
Pred is a multifile predicate this predicate
succeeds for all files that contribute clauses to Pred.56The
current implementation performs a linear scan through all clauses to
establish this set of files. See also clause_property/2.
Note that the relation between files and predicates is more complicated
if include/1
is used. The predicate describes the owner of the predicate.
See
include/1
for details.
