IAMDevMemoryAllocator::CheckMemory (Windows Embedded CE 6.0)

This method tests whether a memory pointer was allocated by the specific instance (device) of the allocator.
Syntax
HRESULT CheckMemory(
const BYTE* pBuffer
);
Parameters
- pBuffer
[in] Pointer to the allocated memory buffer's address.
Return Value
Returns S_OK if the on-board allocator allocated the memory, or S_FALSE if not. Memory that is on the particular device but not allocated will also return S_FALSE.
