PFND3DDDI_CREATESYNCHRONIZATIONOBJECT2CB callback function

Creates a GPU synchronization object that a device context can signal and wait for. Used by WDDM 1.2 and later user-mode display drivers.

Syntax


PFND3DDDI_CREATESYNCHRONIZATIONOBJECT2CB pfnCreateSynchronizationObject2Cb;

_Check_return_ HRESULT APIENTRY CALLBACK* pfnCreateSynchronizationObject2Cb(
  _In_    HANDLE                                hDevice,
  _Inout_ D3DDDICB_CREATESYNCHRONIZATIONOBJECT2 *pData
)
{ ... }

Parameters

hDevice [in]

A handle to the display device (that is, the graphics context) that will own the synchronization object that pfnCreateSynchronizationObject2Cb creates.

pData [in, out]

A pointer to a D3DDDICB_CREATESYNCHRONIZATIONOBJECT2 structure that describes the synchronization object to create.

Return value

Returns one of the following values:

Return codeDescription
S_OK

The synchronization object was successfully created.

E_OUTOFMEMORY

The function could not allocate memory that was required for it to complete.

E_INVALIDARG

Parameters were validated and determined to be incorrect.

 

This function might also return other HRESULT values.

Remarks

The pfnCreateSynchronizationObject2Cb function returns a kernel-mode handle to the newly created synchronization object in the hSyncObject member of the D3DDDICB_CREATESYNCHRONIZATIONOBJECT2 structure that the pData parameter points to. The user-mode display driver passes this handle in calls to the following functions:
