CcSetBcbOwnerPointer function (ntifs.h)

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.
