Pinning ref objects

[Ioannis Vranos]

Can this approach pin a ref object, in this case a System::String? (just
because C++ programmers like low level programming and not a language
that tries to protect us from ourselves).


int main()
{
using namespace System;

String ^s="Hello";

pin_ptr<unsigned char> p= *reinterpret_cast<unsigned char **>(&s);
}

int main()

String ^s="Hello";

pin_ptr<unsigned char> p= *reinterpret_cast<unsigned char **>(&s);

Or perhaps this style:


value class ValueClass
{};

ref class RefClass{};


int main()
{
using namespace System;

RefClass obj;

ValueClass ^h=reinterpret_cast<ValueClass ^>(%obj);

// obj is pinned
pin_ptr<ValueClass> p= &*h;

// Unpin
p=nullptr;
}
