## Detailed Description

### template<class T>
struct Steinberg::FPtrNuller< T >

Template definition for classes that help guarding against dangling pointers.

A stack allocated object of this type automatically resets an at construction time passed pointer to null when it reaches the end of its scope.
Intended usage:

int* pointerToInt = 0;
{
int i = 1;
pointerToInt = &i;
Steinberg::FPtrNuller<int> ptrNuller (pointerToInt);
// Do something with pointerToInt.
} // No dangling pointer here, pointerToInt is reset to 0 by destructor of ptrNuller.
