coroutining object provides a portable abstraction over how
common coroutining predicates are made available by the supported
backend Prolog systems (ECLiPSe, LVM, SICStus Prolog, SWI-Prolog,
Trealla Prolog, and YAP) that provide them. Partial support for XSB is
provided (the predicate
frozen/2 is not available and calls to it
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.

To load all entities in this library, load the

To test this library predicates, load the

Load this library from your application loader file. To call the coroutining predicates using implicit message sending, add the following directive to any object or category calling the predicates (adjust the list to the predicates actually called):
:- uses(coroutining, [ dif/2, dif/1, freeze/2, frozen/2, when/2 ]).
