RAW_READ_INFO structure (ntddcdrm.h)

  • Article

The RAW_READ_INFO structure is used in conjunction with the IOCTL_CDROM_RAW_READ request to read data from a CD-ROM in raw mode.

Syntax

typedef struct __RAW_READ_INFO {
  LARGE_INTEGER   DiskOffset;
  ULONG           SectorCount;
  TRACK_MODE_TYPE TrackMode;
} RAW_READ_INFO, *PRAW_READ_INFO;

Members

DiskOffset

Contains an offset into the CD-ROM disc where data will be read. You can calculate this offset by multiplying the starting sector number for the request times 2048.

SectorCount

Contains the number of sectors to read.

TrackMode

Contains an enumerator of type TRACK_MODE_TYPE that indicates the type of the track mode.
