How to: Declare Pinning Pointers and Value Types

A value type can be implicitly boxed. You can then declare a pinning pointer to the value type object itself and use a pin_ptr to the boxed value type.

Example

Code

// pin_ptr_value.cpp
// compile with: /clr
value struct V {
   int i;
};

int main() {
   V ^ v = gcnew V;   // imnplicit boxing
   v->i=8;
   System::Console::WriteLine(v->i);
   pin_ptr<V> mv = &*v;
   mv->i = 7;
   System::Console::WriteLine(v->i);
   System::Console::WriteLine(mv->i);
}
