dif
¶
The dif
object provides a portable abstraction over how the
dif/2
predicate is made available by the supported backend Prolog
systems that implement it (B-Prolog, ECLiPSe, Scryer Prolog, SICStus
Prolog, SWI-Prolog, Trealla Prolog, XSB, and YAP).
Calls to the library predicates are inlined when compiled with the
optimize
flag turned on. In this case, there is no overhead compared
with calling the abstracted predicates directly.
