C++ style question

[gaf at blu.org (Jerry Feldman)]

This is more of a style issue. I have a standalone function that I want to 
use in a number of different classes, let's call it foo.
On one hand I could simply define and build the function in it's own C++ 
file, or I could alternatively make it a class, either use the constructor 
or simply define a static function. 
Case 1:
foo.H
class foo {
public:
	foo(arg1, arg2, arg3);
};
foo.cc
foo::foo(arg1, arg2, arg3)
Case 2: Use a static class function
foo.H
class foo {
public:
	foo() {};
        static void foofunc(arg1, arg2, arg3);
};
foo.cc
foo::foo(arg1, arg2, arg3)
{
        do something
}
case 2:
static foo:foofunc(arg1, arg2, arg3)
{
        do something
}

What I am looking for is simply an opinion on style. 
In my specific case the one of the arguments (passed by reference) is an 
STL container that is populated. 

Currently, my thoughts are simply to define the function outside of any 
class (as one would in C).
