D3DDDICB_WAITFORSYNCHRONIZATIONOBJECTFROMCPU is used with pfnWaitForSynchronizationObjectFromCpuCb to wait for a monitored fence to reach a certain value.
ObjectCount [in]The number of synchronization objects in the ObjectHandleArray and fence values in the FenceValueArray.
ObjectHandleArray [in]An array of kernel-mode handles to the synchronization events to wait for.
FenceValueArray [in]An array of 64-bit monitored fence values to wait for, each corresponding to an object in the ObjectHandleArray.
hAsyncEvent [in]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.
Flags [in]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. |
