Miscellaneous Functions
type-of
(type-of value)
type-of returns an atom indicating the type of value, or nil if
value is nil.
addr-of
(addr-of value)
addr-of returns the raw immediate value of its argument as an int. For
conses, strings, and funptrs, this is their memory address (hence the
name). For ints, floats, and atoms, this returns their raw bytes
interpreted as a signed 2's-complement integer.
set
(set atom value)
set changes the value associated with atom in the syms-alist, or
creates the association if it does not already exist. It then returns
value.
unset!
(unset! atom)
unset deletes the topmost entry for atom in the syms-alist, and
returns the value atom previously held.
fun
(fun atom)
fun returns the function associated with atom in the funs-alist, or
nil if no such function exists.
print
(print &rest values)
print outputs each of its arguments to standard output, separated by
spaces and followed by a newline.
