D3DDDICB_WAITFORSYNCHRONIZATIONOBJECTFROMGPU structure (d3dumddi.h)

  • Article

D3DDDICB_WAITFORSYNCHRONIZATIONOBJECTFROMGPU is used with pfnWaitForSynchronizationObjectFromGpuCb to wait for a monitored fence to reach a certain value.

Syntax

typedef struct D3DDDICB_WAITFORSYNCHRONIZATIONOBJECTFROMGPU {
  [in] HANDLE              hContext;
  [in] UINT                ObjectCount;
  [in] const D3DKMT_HANDLE *ObjectHandleArray;
  union {
    [in] const UINT64 *MonitoredFenceValueArray;
    [in] UINT64       FenceValue;
         UINT64       Reserved[8];
  };
} D3DDDICB_WAITFORSYNCHRONIZATIONOBJECTFROMGPU;

Members

[in] hContext

A kernel-mode handle to the context stream in which a wait for the synchronization events in the array that the ObjectHandleArray member specifies is inserted.

[in] ObjectCount

The number of synchronization events in the ObjectHandleArray array and fence values in MonitoredFenceValueArray arrays.

[in] ObjectHandleArray

An array of kernel-mode handles to the synchronization events that the context that is specified by the hContext member waits for.

[in] MonitoredFenceValueArray

An array of 64-bit monitored fence values to wait for, each value corresponding to a synchronization object in ObjectHandleArray.

[in] FenceValue

Fence value to wait for when the input object is of type D3DDDI_FENCE.

Reserved[8]

This member is reserved and should be set to zero.
