SafeHandle.SetOwnership(false)

[HosamAly]

I have a SafeHandle returned from an external function. I want to set the "ownsHandle" property to false, but the problem is that I'm only able to do this in the constructor. Is there a way to do it? Here is an example:

class MyHandle : SafeHandleZeroOrMinusOneIsInvalid {
MyHandle() : base(true) {}

\[ReliabilityContract(Consistency.WillNotCorruptState, Cer.Success)\]
protected override bool ReleaseHandle() {
    externalReleaseHandle(handle);
}

\[DllImport("MyLib.dll")\] extern void externalReleaseHandle(IntPtr handle);

}

class MyClass {
public static void main(string[] args) {
MyHandle h1 = externalCreateHandle();
MyHandle h2 = externalGetPointer(h1);
}

\[DllImport("MyLib.dll")\] extern void externalCreateHandle();
\[DllImport("MyLib.dll")\] extern void externalGetPointer(MyHandle handle);

}

The problem is that I want h1 to be released, but not h2. I thought about using GC.SuppressFinalize(h2), but still calling Dispose() would cause the same problem. Is there a way to do this?

Would h2.DangerousAddRef() (without DangerousRelease()) suffice to achieve my objective?

Sorry, I noticed that this would result in a memory leak for the SafeHandle itself.
