“Generic” iterator in c++

Question

I have:

void add_all_msgs(std::deque::iterator &iter);

How can I make that function \"generic\", so it can take any kind

Answer 1

#include 
#include 
#include 
#include 
using namespace std;

template
void add_all_msgs(T &iter)
{

}

int _tmain(int argc, _TCHAR* argv[])
{
    std::deque::iterator it1;
    std::vector::iterator it2;
    std::list::iterator it3;

    add_all_msgs(it1);
    add_all_msgs(it2);
    add_all_msgs(it3);


    return 0;
}
