call/cc ⇝


<Lisp, programming>

(call/cc) A Lisp control function that takes a function f as its argument and calls f, passing it the current continuation, which is itself a function, k. k, which represents the context of the call to call/cc, takes the result of call/cc (which is the result of f) and returns the final result of the whole program. Thus if, for example, the final result is to print the value returned by call/cc then anything passed to k will also be printed.

E.g, in Scheme:

 (define (f k)
	 (k 1)
	 (k 2)

 (display (call-with-current-continuation f))

Will display 1.
