Removes the memory registration for an application-defined buffer.
HRESULT DeregisterMemory( [in] ND_MR_HANDLE *hMr, [in] OVERLAPPED *pOverlapped );
The handle to the memory region. The INDAdapter::RegisterMemory method returns the handle.
A pointer to an OVERLAPPED structure that must remain valid for the duration of the operation.
When you implement this method, you should return the following return values. If you return others, try to use well-known values to aid in debugging issues.
The operation completed successfully.
The memory region is in process of being freed. Completion will be reported asynchronously.
The hMr parameter is not valid.
The memory region still has memory windows bound to it.
