DeviceDsmAddDataSetRange function (ntddstor.h)

The DeviceDsmAddDataSetRange function adds a data set range to the system buffer for an IOCTL_STORAGE_MANAGE_DATA_SET_ATTRIBUTES request.

Syntax

BOOLEAN DeviceDsmAddDataSetRange(
  PDEVICE_DSM_INPUT Input,
  ULONG             InputLength,
  LONGLONG          Offset,
  ULONGLONG         Length
);

Parameters

Input

Pointer to the DEVICE_DSM_INPUT structure to which to add the data set range.

InputLength

The length, in bytes, of the entire payload of the IOCTL_STORAGE_MANAGE_DATA_SET_ATTRIBUTES request.

Offset

The offset from the start of the DEVICE_DSM_INPUT structure at which the data set range starts, in bytes.

Length

Return value

Returns TRUE if the data set range was successfully added, or FALSE otherwise.
