Unique class type Id that is safe and holds across library boundaries

Question

I would appreciate any help as C++ is not my primary language.

I have a template class that is derived in multiple libraries. I am trying to figure out a way to uniq

Answer 1

You can do the following:

#include 


template 
class blah
{
public:
    static const int cid = id; 
};

int main(int argc, char *argv[])
{
    std::cout << blah<>::cid << " " << blah<10>::cid << std::endl;

}

I don't know if it's a good idea though. The blah<> part is a bit unintuitive too. Maybe you're better off assigning them ids manually, or you can create a base type, give it a template argument with your class id.
