_D3DKMT_WAITFORSYNCHRONIZATIONOBJECTFROMCPU structure

Description

D3DKMT_WAITFORSYNCHRONIZATIONOBJECTFROMCPU is used with D3DKMTWaitForSynchronizationObjectFromCpu to wait for a monitored fence to reach a certain value.

Members

hDevice [in]

The device handle to wait on.

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.
