What information do you want to know about it?

For where it is defined, and how it is highlighted, do:

:verbose hi Function

Or did you want something else?

I want to know how it is defined, i checked other syntax commands,
they are defined as regular expressions, so even the "Function"
must be defined as one, But i couldn't find it in the list, when i
type
"syntax" without any parameter.

Well, if you type

        :verbose hi Function

followed by <Enter>, the answer will be on two lines: the value of the
current colors for the Function highlight group, and the script where it
was last set (or nothing for never set or set manually by typing the :hi
command). For instance on my system it says

        Function        xxx links to Identifier
                Last set from /usr/local/share/vim/vim73/syncolor.vim

The Function syntax group is never defined. It is meant to be available
so syntax scripts can link to it: for instance

        :verbose hi VimFuncName

returns

        VimFuncName    xxx links to Function
                Last set from /usr/local/share/vim/vim73/syntax/vim.vim

which means that the syntax group VimFuncName, defined by
syntax/vim.vim, will use the colors defined for the Function group
(which itself links to the Identifier group, see above). The reason
there are distinct Function and Identifier groups is so colorschemes
can, if desired, define different colors for them.

The command

        :verbose hi

will tell you what _all_ highlight groups are and where they were
defined, but beware: there are a lot of them. You can capture this
output (and then paste it for searching), see ":help :redir" and ":help
'more'".


Best regards,
Tony.

i am trying to write a regular expression to search
for the c function, the following doesnt seem to work
very well.

[a-z|_|0-9]\+(.\+[^\r\n]\+);\C

for exmaple, in the following example the above re
is selecting the whole text startnig from new_func
till end-of-file. what's wrong with re ?

code
code
new_func(int a, int b);
code
code
end-of-file

For me, your regular expression matches just what you want, however it
looks kind of strange:

> [a-z|_|0-9]\+(.\+[^\r\n]\+);\C

1) What are the 2 | in the first collation for? I think you can leave
them out.
2) the [^\r\n] is not needed I believe, since collations usually don't
match line breaks. See :h /\_ for details,

regards,
Christian
