pfnReserveGPUVirtualAddressCb reserves an address range in the current process graphics processing unit (GPU) virtual address space. The address range is only reserved, there is no actual memory behind it.
The user mode driver may choose the base GPU virtual address to use for the reservation by specifying a non-NULL value for BaseAddress. The video memory manager will use the specified range if it is available. If the range intersects with an existing range, the operation will fail. The user mode driver may pass a NULLBaseAddress to let the video memory manager pick a base address.
When the user mode driver chooses to let the video memory manager pick a base address for the GPU virtual address range, it may choose to constrain the range that the video memory manager will consider by specifying non-NULL values for MinimumAddress and MaximumAddress. The video memory manager will ensure that the allocated GPU virtual address range is entirely contained in the range. The user mode driver may specify only a MinimumAddress (MaximumAddress being assumed to be the end of the address space) or only specify a MaximumAddress (MinimumAddress being assumed to be 0).

pData [in, out]
A pointer to a D3DDDI_RESERVEGPUVIRTUALADDRESS structure that describes the operation to perform.
If this callback function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
