Hi Everyone,

    Could anyone explain me how I can directly return from a defun in elisp.

    basically I have following type of code:

    ......... body of defun ............
    ..........................................
    (if condition01
            (return 10)  ; return from this defun with value 10
         t)

    .......... rest body of defun ....
   ...........................................

If you really must:

(defun whatever ()
  (catch 'return
    (... body of defun ...
       (if condition01
           (throw 'return 10))
       ... rest body of defun ...
)))

(require 'cl)

(defun* fun ()
  ...
  (return-from fun 10)
  ...)
