RE: ctags

[Khachaturov, Vassilii]

I use cscope instead, and vim's front-end to it.
(Emacs fans: XEmacs has a similar support, see cscope page on sourceforge).

Much more powerful than plain tags,
because it allows also things like 
"where are all the calls to this function",
but you still can jump about with ^T/^]

At top level of the kernel source tree (/usr/src/linux) do

find . -name '*.[hc]' -print > cscope.files
cscope -b -k -I/usr/src/linux/include

In the .vimrc used for kernel editing, do:
cscope add /usr/src/linux/cscope.out /usr/src/linux
set cstag

And do :help cscope to see what this thing is about...
Or, for a quick start, just do :cs

See also cscope on sourceforge.

HTH,
	Vassilii

find -name '*.[ch]' | ctag -L- &
echo "set tags-tags">>.vimrc

Hi
                   Thanks for the reply. To get the definition of the
functions above  is enough. Now if there are more than one definition of the
same function how to get all the definitions
