Is it safe to remove an item in a std::map with scoped_ptr? Lile,

std::map<std::string, boost::scoped_ptr<CFoo*>> lmap;

boost::scoped_ptr<CFoo> item1(new CFoo);
boost::scoped_ptr<CFoo> item2(new CFoo);

lmap["item1"] = item1;
lmap["item2"] = item2;


std::map<std::string, boost::scoped_ptr<CFoo*>>::iterator iter;
iter = lmap.find("item1");
lmap.erase(iter)

Thanks!

This shouldn't even compile. You probably mean `scoped_ptr`. – us2012 Sep 25 '13 at 00:24
is scoped_ptr ever copyable? – billz Sep 25 '13 at 00:26
No, you can't copy a `scoped_ptr`. – us2012 Sep 25 '13 at 00:34
The longer I think about it, the more I'm wondering whether this approach is a sensible way to address whatever the problem might be. Why not use a `map `? Is `CFoo` so huge that it would cause troubles? – us2012 Sep 25 '13 at 00:39
