Now what's wrong with this STL code

[GCDEF]

Same code as last thread but different error message. I went from VC2008 to VC2012 and I'm getting this error. Not sure why. Previous error was fixed by #include <iterator> on a different computer. Current computer is generating this error.

error C2784: void STLCopy(tSTLContainer *,const tSTLContainer *)' : could not deduce template argument for 'tSTLContainer *' from 'std::vector<_Ty,_Alloc>'

template 
<
	class tSTLContainer			// The type of STL container to copy.
>
void STLCopy (tSTLContainer* outDest, const tSTLContainer* inSource)
{
	copy(inSource->begin(), inSource->end(), insert_iterator<tSTLContainer>(outDest, outDest->begin()));
}

Once again, never mind. Changing pointers to references fixed it, but I'm not sure why.
