  • Artikel

This routine retrieves an object that was inserted in the Silo without incrementing the reference count.

Syntax

NTSTATUS PsGetPermanentSiloContext(
  [in] PESILO Silo,
  [in] ULONG  ContextSlot,
       PVOID  *ReturnedSiloContext
);

Parameters

[in] Silo

The silo in which the object was inserted. This parameter is required and it cannot be NULL.

[in] ContextSlot

The read-only slot that was previously allocated byPsAllocSiloContextSlot and made read-only by PsMakeSiloContextPermanent.

ReturnedSiloContext

A pointer to a caller-allocated variable that receives the address of the existing object. This parameter is required and it cannot be NULL.

Return value

The following NT status codes are returned.

Return code Description
STATUS_NOT_FOUND
 The slot is empty. This is an error code.
STATUS_NOT_SUPPORTED 
 The slot is not read-only and it cannot safely retrieve the object. This is an error code.
STATUS_SUCCESS
 The operation completed successfully.

Remarks

A successful call to PsGetPermanentSiloContext does not increment the reference count on the object that the ReturnedSiloContext parameter points to. The returned object pointer is valid as long as there is a valid reference on the silo object.
