The D3DDDICB_SIGNALFLAGS structure describes signaling behavior in a call to the pfnSignalSynchronizationObjectCb or pfnSignalSynchronizationObject2Cb functions.
SignalAtSubmissionA UINT value that specifies whether a context should signal synchronization objects when the previously queued packet is submitted rather than completed (which is the default behavior).
Setting this member is equivalent to setting the first bit of the 32-bit Value member (0x00000001).
EnqueueCpuEventA UINT value that modifies the behavior of the pfnSignalSynchronizationObject2Cb function.
When this member is set:
The event specified by the CpuEventHandle member of the D3DDDICB_SIGNALSYNCHRONIZATIONOBJECT2 structure is signaled when all contexts specified in D3DDDICB_SIGNALSYNCHRONIZATIONOBJECT2 process the signal command.
Members of the D3DDDICB_SIGNALSYNCHRONIZATIONOBJECT2 structure that the pfnSignalSynchronizationObject2Cb function's pData parameter points to are restricted as follows:
Setting this member is equivalent to setting the second bit of the 32-bit Value member (0x00000002).
Supported starting with Windows 8.
AllowFenceRewindA UINT value that indicates whether an intentional fence rewind is allowed. When set TRUE, the fence can be rewound to a queued fence that is behind the current one.
Supported starting with Windows 10 (WDDM 2.0).
DXGK_SIGNAL_FLAG_INTERNAL0This member is reserved and should be set to zero.
ReservedThis member is reserved and should be set to zero.
ValueA member in the union that is contained in D3DDDICB_SIGNALFLAGS that can hold one 32-bit value that identifies signaling behavior.
