(atoms-family)

(atoms-family format [symbol1 symbol2 ...])


Determine which function names are being used.


This function lists all the pre-defined and user-defined functions in the current session. The format argument specifies how the information is returned. Format is an integer value of 0 or 1.

Format Meaning
0 Defined functions are returned as a list.
1 Defined functions are returned as a list of strings.

The optional argument [symbol1symbol2 ...] is a list of strings representing symbols. It is used to confirm whether the function names are defined in the current session. If symbol1, symbol2, ... are defined, LISP returns the symbols as strings, depending on the format chosen. If one is not defined, a nil is returned in place of the symbol.

Examples

Code Returns
(setq hi "Greeting 1")  
(setq bye "Greeting 2")  
(atoms-family 0 '("hi" "bye")) (HI BYE)
(atoms-family 0 '("hi" "hello" "bye")) (HI nil BYE)
(atoms-family 1 '("hi" "bye")) ("HI" "BYE")
