STARTING_LCN_INPUT_BUFFER

The STARTING_LCN_INPUT_BUFFER structure provides the starting LCN to the DeviceIoControl FSCTL_GET_VOLUME_BITMAP operation.

typedef struct {
  LARGE_INTEGER StartingLcn;
} STARTING_LCN_INPUT_BUFFER, *PSTARTING_LCN_INPUT_BUFFER;

Members

StartingLcn
The LCN from which the DeviceIoControl FSCTL_GET_VOLUME_BITMAP operation should start when describing a bitmap. The StartingLcn member will be rounded down to a file-system-dependent rounding boundary, and that value will be returned. This value should be an integral multiple of eight.

Requirements

  Windows NT/2000: Requires Windows 2000.
  Windows 95/98: Unsupported.
  Header: Declared in Winioctl.h.
