PFND3D12DDI_QUEUEPROCESSINGWORK_CB_0062 callback function (d3d12umddi.h)

PfnQueueProcessingWorkCb is provided by the runtime and called by user mode drivers to register and queue work items.

The runtime is responsible for managing threads, either directly, or through a Thread Pool. The UMD will not have any control over which thread the work is processed on. Work will be processed in the order it was received. PfnQueueProcessingWorkCb may be called from multiple threads concurrently and is thread safe (runtime will serialize).

)
{...}

Parameters

[in] hRTDevice

The handle of the device for the driver to use when it calls back into the runtime.
