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.
