where is a function defined

where is a function defined

[Z. Huang]

  load-path seems to be not I wanted. I have to go to each of the directories
to find a symbol that I need. Is there any simpler way to find the definition
of a function?

Maybe I misunderstood the question, but what is wrong with using `C-h
C-f' (describe-function)?

    I need to find the lisp code for a function, not only the
description. Thanks for the response anyway.

describe-function's output tells you which file contains the function
definition, e.g.:

do-auto-fill is a compiled Lisp function in `simple'.

This tells you to look in simple.el.

       I need to find the lisp code for a function, not only the
   description. Thanks for the response anyway.

describe-function shows a "link" to the elisp code for a function.
For example, this is the docstring for describe-function, the link to
the elisp code be be retrived by pressing the `help-fns' link thing.

describe-function is an interactive compiled Lisp function in `help-fns'.
It is bound to C-h f, <menu-bar> <help-menu> <describe> <describe-function>.
(describe-function FUNCTION)

Display the full documentation of FUNCTION (a symbol).

M-x find-function RET

Does this help?

XEmacs has "find-function".  I've forgotten if Emacs has it.  It will
do the path searching for you.
