);

[in] Silo

The silo from which the object is to be removed. This parameter is required and it cannot be NULL.

[in] ContextSlot

A slot allocated by the PsAllocSiloContextSlot routine.

RemovedSiloContext

A pointer to a caller-allocated variable that receives the address of the removed object. This parameter is optional and can be NULL.

Return value

Return code	Description
STATUS_NOT_FOUND	The slot is empty. This is an error code.
STATUS_NOT_SUPPORTED	The slot is read-only and it cannot be modified. This is an error code.
STATUS_SUCCESS	The operation completed successfully.
