Syntax:function-lambda-list function &optional errorp t
verbose t

Returns the parameters of the function it is called on. function should be either a function or a function name. When function is a function name, and there is no corresponding global function definition for that name,erropdetermines what happens. Iferrorp is non-nil (the default) an error is returned. Iferrorpisnil, the symbol:none is returned. The third argument,verbose determines whether or not to print out a short message whenever the arglist is being extracted for a function that is otherwise traced, monitored, or haddefadvice called on it. This function provides a common name between the Harlequin Lisp products for what Lucid historically calledarglist.

Examples:

(function-lambda-list 'memq) =>
(LIQUID::X LIQUID::L)

(pprint (function-lambda-list 'REMOVE-ADVICE)) =>
(ADVISED-FN &OPTIONAL ADVICE-NAME
             &KEY (VERBOSE T)
              &AUX (FN-NAME (UNDERLYING-NAME ADVISED-FN))
                     OLD-DATA)
