how to find delaration of a variable

how to find delaration of a variable

[Lowell Kirsh]

Is there an elisp function similar to find-variable-at-point that would 
work for non-lisp code? I'd like to use it to jump to the declaration of 
whatever variable is at point.

First run
etags *.c *.h

and then press M-. on the variable in question (specifying the local
TAGS file that etags generated, if you get asked for it).

thanks. it works well most of the time. I have one question though: 
sometimes it will take me to the declaration of the a variable of the 
same name but in a different file. Is there any way I can make sure it 
looks in the current file for the declaration before going to other file?

Dunno, but M-0 M-. will take you to the next occurrence.  Maybe that's
good enough?

You might also try M-x imenu RET.  It operates on the current file
only.
