Compiler Error C3833

'type' : invalid target type for pointer_type

Remarks

An interior_ptr or pin_ptr was declared incorrectly.

Examples

The following example generates C3833:

// C3833.cpp
// compile with: /clr

ref class MyClass {
public:
   int data;
   MyClass() : data(35) {}
};

int main() {
   interior_ptr<MyClass> p;   // C3833

   // OK
   MyClass ^ h_MyClass = gcnew MyClass;
   interior_ptr<int> i = &(h_MyClass->data);
   System::Console::WriteLine(*i);
}

The following example generates C3833:

// C3833b.cpp
// compile with: /clr /c
ref class G {
public:
   int i;
};

int main() {
   G ^ pG = gcnew G;
   pin_ptr<G> ppG = &pG;   // C3833 can't pin a whole object

   // OK
   pin_ptr<int> ppG2 = &pG->i;
   *ppG2 = 54;
   int * pi = ppG2;
   System::Console::WriteLine(*pi);
   System::Console::WriteLine(*ppG2);

   *pi = 55;
   System::Console::WriteLine(*pi);
   System::Console::WriteLine(*ppG2);

   *ppG2 = 56;
   System::Console::WriteLine(*pi);
   System::Console::WriteLine(*ppG2);
}
