Syntax:
invoke-restart restart &rest arguments => result*
Arguments and Values:
restart---a restart designator.
argument---an object.
results---the values returned by the function associated with restart, if that function returns.
Description:
Calls the function associated with restart, passing arguments to it. Restart must be valid in the current dynamic environment.
Examples:
(defun add3 (x) (check-type x number) (+ x 3)) (foo 'seven) >> Error: The value SEVEN was not of type NUMBER. >> To continue, type :CONTINUE followed by an option number: >> 1: Specify a different value to use. >> 2: Return to Lisp Toplevel. >> Debug> (invoke-restart 'store-value 7) => 10
Side Effects:
A non-local transfer of control might be done by the restart.
Affected By:
Existing restarts.
Exceptional Situations:
If restart is not valid, an error of type control-error is signaled.
See Also:
find-restart, restart-bind, restart-case, invoke-restart-interactively
Notes:
The most common use for invoke-restart is in a handler. It might be used explicitly, or implicitly through invoke-restart-interactively or a restart function.
Restart functions call invoke-restart, not vice versa. That is, invoke-restart provides primitive functionality, and restart functions are non-essential ``syntactic sugar.''
