FsRtlSplitLargeMcb function (ntifs.h)
The FsRtlSplitLargeMcb routine inserts a hole into the mappings in a map control block (MCB).
BOOLEAN FsRtlSplitLargeMcb( [in] PLARGE_MCB Mcb, [in] LONGLONG Vbn, [in] LONGLONG Amount );
Pointer to the MCB structure.
Starting virtual block number (VBN) of the range of mappings to be shifted upward by Amount to make room for the hole.
Number of sectors (VBNs) in the hole to be created.
FsRtlSplitLargeMcb returns TRUE if the hole was successfully created, FALSE otherwise.
A hole is a range of unmapped VBNs that form a gap between two mappings.
If a pool allocation failure occurs, FsRtlSplitLargeMcb raises a STATUS_INSUFFICIENT_RESOURCES exception. To gain control if this pool allocation failure occurs, the driver should wrap the call to FsRtlSplitLargeMcb in a try-except or try-finally statement.
