Besides Boost, where can I get a single-file smart pointer implementation for C++?

Question

I want to start using smart pointers in my code but I don't really want to use Boost because it's so huge.

Can anyone recommend a simple, one-file smart pointer implementation?

Thanks, Boda Cydo.

Answer 1

Unfortunately, smart pointers are not all that simple, so the implementation may be quite complicated. Having said that, if you are using g++ you get things like shared_ptr without having to use Boost:

#include <memory>
using namespace std;

int main() {
    shared_ptr <int> p( new int );
}

but you will have to compile with the -std=c++0x flag.

You could upgrade to a recent-enough compiler and use what TR1 gives you. The compiler I use has included TR1 pre-releases for many years.
