The CcSetBcbOwnerPointer routine sets the owner thread pointer for a pinned buffer control block (BCB).
Syntax
void CcSetBcbOwnerPointer(
[in] PVOID Bcb,
[in] PVOID OwnerPointer
);
Parameters
[in] Bcb
Pointer to a pinned BCB structure that is owned by the current thread.
[in] OwnerPointer
A valid resource owner pointer, which means a pointer to an allocated system address, with the low-order two bits set. This address may not be deallocated until after the BCB is unpinned by a subsequent call to CcUnpinDataForThread.
Return value
None
Remarks
File systems call CcSetBcbOwnerPointer to set the resource owner for a pinned buffer control block (BCB), in cases where another thread will unpin the BCB and thus the current thread can exit.
Each call to CcSetBcbOwnerPointer must be matched by a subsequent call to CcUnpinDataForThread, which must be called with the same owner pointer.
BCBs that have been modified by CcSetBcbOwnerPointer cannot be unpinned by calling CcUnpinData.
