D3DKMT_WAITFORSYNCHRONIZATIONOBJECTFROMCPU structure (d3dkmthk.h)

  • Article

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;
  void                                             D3DKMT_PTR(
    const D3DKMT_HANDLE *unnamedParam1,
    ObjectHandleArray   unnamedParam2
  );
  void                                             D3DKMT_PTR(
    const UINT64    *unnamedParam1,
    FenceValueArray unnamedParam2
  );
  void                                             D3DKMT_PTR(
    HANDLE      unnamedParam1,
    hAsyncEvent unnamedParam2
  );
  [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.

void D3DKMT_PTR( const D3DKMT_HANDLE *unnamedParam1, ObjectHandleArray unnamedParam2)

void D3DKMT_PTR( const UINT64 *unnamedParam1, FenceValueArray unnamedParam2)

void D3DKMT_PTR( HANDLE unnamedParam1, hAsyncEvent unnamedParam2)

[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.
