The pfnDisableDeferredStagingResourceDestruction function disables the deferred destruction of staging resources.

Syntax

PFND3D10DDI_DISABLE_DEFERRED_STAGING_RESOURCE_DESTRUCTION_CB Pfnd3d10ddiDisableDeferredStagingResourceDestructionCb;

void Pfnd3d10ddiDisableDeferredStagingResourceDestructionCb(
  D3D10DDI_HRTCORELAYER unnamedParam1
)
{...}

Parameters

unnamedParam1

hRuntimeDevice [in]

A handle to a context for the core Microsoft Direct3D 10 runtime. This handle is supplied to the driver in a call to the driver's CreateDevice(D3D10) function.

Return value

None

Remarks

By default, the Direct3D runtime defers the destruction of staging resources, until a call to the user-mode display driver's ResourceIsStagingBusy function indicates that the graphics pipeline no longer uses the resources. The runtime defers the destruction of staging resources because the destruction of a staging resource, while still in use, might cause the processor to block until the resource is no longer used.

If the user-mode display driver can ensure that this type of block can be avoided, the driver can call pfnDisableDeferredStagingResourceDestruction to disable the deferred destruction behavior.
