Here is cfind, which prints out the entire function.  It assumes a lot
about indenting styes, though.
It's easy to hack it to print just the name...

You could also look at "calls", a sort of cross-reference generating
program, and at "cpr", which emboldens function names.

#! /bin/sh
if [ "x$1" = "x" -o "x$2" = "x" ]
then
    echo "Usage: $0 function file [file...]" 1>&2
    exit 1
fi

pat="$1"
echo "Looking for $pat" 1>&2
shift
for i
do
    echo "$i:" 1>&2 ; cat "$i" |
    sed -n -e '/^[ 	]*[a-zA-Z0-9]*[ 	]*[*]*[ 	]*'"$pat"'/,/^}/p'
done

#end

disclaimer:  I've not looked at cfind for several years!
