D3DKMT_WAITFORSYNCHRONIZATIONOBJECTFROMCPU structure (d3dkmthk.h)
D3DKMT_WAITFORSYNCHRONIZATIONOBJECTFROMCPU is used with D3DKMTWaitForSynchronizationObjectFromCpu to wait for a monitored fence to reach a certain value.
Syntax
typedef struct _D3DKMT_WAITFORSYNCHRONIZATIONOBJECTFROMCPU {
[in] D3DKMT_HANDLE hDevice;
[in] UINT ObjectCount;
[in] const D3DKMT_HANDLE *ObjectHandleArray;
[in] const UINT64 *FenceValueArray;
[in] HANDLE hAsyncEvent;
[in] D3DDDI_WAITFORSYNCHRONIZATIONOBJECTFROMCPU_FLAGS Flags;
} D3DKMT_WAITFORSYNCHRONIZATIONOBJECTFROMCPU;
Members
[in] hDevice
The device handle to wait on.
[in] ObjectCount
The number of synchronization objects in the ObjectHandleArray and fence values in the FenceValueArray.
[in] ObjectHandleArray
An array of kernel-mode handles to the synchronization events to wait for.
[in] FenceValueArray
An array of 64-bit monitored fence values to wait for, each corresponding to an object in the ObjectHandleArray.
[in] hAsyncEvent
When not NULL, specifies the event to be signaled when the wait condition is satisfied. When NULL, the call will not return until the wait condition is satisfied.
[in] Flags
A D3DDDI_WAITFORSYNCHRONIZATIONOBJECTFROMCPU_FLAGS structure describing the operation.
| Value | Meaning |
|---|---|
| WaitAny | |
| FALSE | The wait condition is considered to be satisfied when all input synchronization objects are signaled to the corresponding input fence values or greater. |
| WaitAny | |
| TRUE | The wait condition is considered to be satisfied when any of the input synchronization objects is signaled to the corresponding input fence value or greater. |
