How to return a NULL to boost::sharedPtr

[AJTech]

I am having something like

typedef boost::shared_p tr<myClass1> MyClass1Ptr;

MyClass1Ptr Function( int key,std::map<in t,MyClass1Ptr> _Map)
{
std::map<int,My Class1Ptr>::ite r i = _Map.find(key)
if(i = _Map.end())
{
return NULL;
}
}

A shared pointer is an object that manages a pointer to a dynaically allocated object.

You do not put NULL in a shared pointer object. Instead you delete the shared pointer. That will call the shared pointer destructor where the reference count may or may not require the managed object to be deleted.
