D3DKMTFreeGpuVirtualAddress function (d3dkmthk.h)
D3DKMTFreeGpuVirtualAddress releases a range of graphics processing unit (GPU) virtual addresses, which was previously reserved or mapped.
Syntax
NTSTATUS D3DKMTFreeGpuVirtualAddress(
[in] const D3DKMT_FREEGPUVIRTUALADDRESS *unnamedParam1
);
Parameters
[in] unnamedParam1
A pointer to a D3DKMT_FREEGPUVIRTUALADDRESS structure that describes the operation.
Return value
| Return code | Description |
|---|---|
| STATUS_SUCCESS | The device context was successfully created. |
| STATUS_INVALID_PARAMETER | Parameters were validated and determined to be incorrect. |
This function might also return other NTSTATUS values.
Remarks
The freed virtual address should not be accessed immediately after the call. If there are outstanding MapGpuVirtualAddress and UpdateGpuVirtualAddress operations, which reference the virtual address, they will be ignored after the virtual address is freed. A new virtual address range can be allocated in place of the freed one immediately after return from the function.
