Module (chicken continuation)
This module provides a more powerful interface for continuations than that provided by call/cc.
More information about this continuation API can be found in the paper A Better API for First-Class Continuations by Marc Feeley.
- continuation-capture PROCEDUREprocedure
Creates a continuation object representing the current continuation and tail-calls PROCEDURE with this continuation as the single argument.
- continuation? Xprocedure
Returns #t if X is a continuation object, or #f otherwise. Please note that this applies only to continuations created by the Continuation API, but not by call/cc, i.e.: (call-with-current-continuation continuation?) returns #f, whereas (continuation-capture continuation?) returns #t.
- continuation-graft CONT THUNKprocedure
Calls the procedure THUNK with no arguments and the implicit continuation CONT.
- continuation-return CONT VALUE ...procedure
Returns the value(s) to the continuation CONT. continuation-return could be implemented like this:
(define (continuation-return k . vals) (continuation-graft k (lambda () (apply values vals))))
