More Grep - Regular Expressions

Hey all! I'm trying to search a file and return all instances of a word, let's say 'foo' in this case, as long as it's not a function name. For example:

1) int foo; //OK
2) //'this is totally fooed up' is also OK
3) int foo (int x, int y) //not ok to return

I've tried a lot of regular expressions but none of them work. Always is foo the function returned.

Here's what I think should work (but doesn't):

grep -E "foo[\s]*[\w]*[^(]" <filename

Any ideas as to why it doesn't work?

UNDOCUMENTED(7) 					     Linux Programmer's Manual						   UNDOCUMENTED(7)

NAME
undocumented - No manpage for this program, utility or function. DESCRIPTION
This program, utility or function does not have a useful manpage. Before opening a bug to report this, please check with the Debian Bug Tracking System (BTS) at <http://bugs.debian.org/> if a bug has already been reported. If not, you can submit a wishlist bug if you want. If you are a competent and accurate writer and are willing to spend the time reading the source code and writing good manpages please write a better man page than this one. Please contact the package maintainer and copy man-pages@qa.debian.org in order to avoid several people working on the same manpage. Even if you are not an accurate writer, your input may be helpful. Writing manual pages is quite easy, the format is described in man(7). The most important and time-consuming task is to collect the information to be put in the new manpage. DIAGNOSTICS
It is possible that the man page for the command you specified is installed and that your manual page index caches are out of sync. You should try running mandb(8). Try the following options if you want more information: foo --help, foo -h, foo -? info foo whatis foo, apropos foo dpkg --listfiles foo, dpkg --search foo locate '*foo*' find / -name '*foo*' Additionally, check the directories /usr/share/doc/foo, /usr/lib/foo. The documentation might be in a package starting with the same name as the package the software belongs to, but ending with -doc or -docs. If you still didn't find the information you are looking for you might consider posting a call for help to debian-user@lists.debian.org. SEE ALSO
info(1), whatis(1), apropos(1), dpkg(8), locate(1), find(1), updatedb(1), undocumented(3), man(7), mandb(8), missing(7). Debian GNU/Linux August 24th, 2003 UNDOCUMENTED(7)
