Function `fboundp' is what you're looking for.
--
Be aware that `fboundp' checks only whether its argument is defined, in the
sense of having something in its function cell. This does not necessarily mean
that the arg is a Lisp function - it could be also a macro or special form. If
you need to test whether the thing in question is in fact a function, use
`functionp'.
