View the official Windows Driver Kit DDI referenceNo description available.
The CcRemapBcb routine maps a buffer control block (BCB) an additional time to preserve it through several calls that perform additional maps and unpins.
Bcb [in]Pointer to the BCB to be remapped.
CcRemapBcb returns a pointer to the remapped BCB with a read-only indicator.
Like CcMapData, CcRemapBcb maps data in a cached file for read access. Note that after CcRemapBcb is called, the data is mapped; but it is not pinned. This distinction is important. Data that is mapped but not pinned cannot safely be modified. To pin the data, use CcPinMappedData, CcPinRead, or CcPreparePinWrite.
