Parameters
pAddress [in]Type: const void * The address used to create the heap. riid
Type: const IID & The globally unique identifier (GUID) for the heap interface (ID3D12Heap). The REFIID, or GUID, of the interface to the heap can be obtained by using the __uuidof() macro. For example, __uuidof(ID3D12Heap) will retrieve the GUID of the interface to a heap. ppvHeap [out]
Type: void ** SAL:
COM_Outptr
A pointer to a memory block. On success, the D3D12 runtime will write a pointer to the newly-opened heap into the memory block. The type of the pointer depends on the provided riid parameter.
Return value
Type: HRESULT This method returns E_OUTOFMEMORY if there is insufficient memory to open the existing heap. See Direct3D 12 Return Codes for other possible return values.Remarks
The heap is created in system memory and permits CPU access. It wraps the entire VirtualAlloc region. Heaps can be used for placed and reserved resources, as orthogonally as other heaps. Restrictions may still exist based on the flags that cannot be app-chosen.Requirements
