How to create free function template which accepts only vector of pointers?

[Unspoken]

Hello,

Currently I have such code:

class MyElem;

typedef std::vector<MyElem*> MyElems;

To clear a memory taken by such vector I am using this code:

void deleteElems(MyElems &Elems)
{
	for (auto i = Elems.begin(); i != Elems.end(); ++i)
	{
		delete((*i));
	}
	Elems.clear();
}

Recently I've introduced another vector:

class MyEntity;

typedef std::vector<MyEntity*> MyEntities;

I could introduce deleteEntities function but I thought to use templates here.
That would be great, to use one function to handle multiple cases. However, I would like to avoid a cryptic error message in case when I pass wrong parameter to the function template. So I would like to contrain somehow to types that can be passed as parameters.
How can I write a function template which accepts only vectors of pointers? Is it possible? I am using C++ 11, no boost library.

Thanks
