FSCTL_GET_INTEGRITY_INFORMATION_BUFFER structure (winioctl.h)

Contains the integrity information for a file or directory. Returned from the FSCTL_GET_INTEGRITY_INFORMATION control code.

Syntax

typedef struct _FSCTL_GET_INTEGRITY_INFORMATION_BUFFER {
  WORD  ChecksumAlgorithm;
  WORD  Reserved;
  DWORD Flags;
  DWORD ChecksumChunkSizeInBytes;
  DWORD ClusterSizeInBytes;
} FSCTL_GET_INTEGRITY_INFORMATION_BUFFER, *PFSCTL_GET_INTEGRITY_INFORMATION_BUFFER;

Members

ChecksumAlgorithm

The checksum algorithm used.

Reserved

Reserved for future use. Set to 0.

Flags

Contains one or more flags.

ChecksumChunkSizeInBytes

Size in bytes of the chunks used to calculate checksums.

ClusterSizeInBytes

Size in bytes of a cluster for this volume. This value must be a power of 2, must be greater than or equal to the sector size of the underlying hardware and must be a power of 2 multiple of the sector size.
