arglist

Arguments: function

Returns two values: if the the argument list of the operator (function, generic function, or macro) specified by the argument is known, it and t are returned. If the argument list is not known (that information can be discarded to save space), nil and nil are returned.

Note that some argument lists may be uninformative (perhaps simply &rest args) when a function does all argument processing within its body. Also, the compiler may have simplified the argument list for its purposes. This function is designed to assist only. The argument list returned, even when the second returned argument is t, may not accurately describe all valid lists of arguments that can be passed to the function. (For example, the &allow-other-keys lambda-list keyword is often dropped.)
