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.
// 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);
}
