Module Name:

    ntddcdvd.h

Abstract:

    This module contains structures and definitions
    associated with DVD ioctls.

    This module is used in conjunction with ntddcdrm.h which contains the
    cdrom specific ioctls which will work on CDVD drives

IOCTL_STORAGE_SET_READ_AHEAD

Requests that the storage device skip to TargetAddress once it has run across
TriggerAddress during the course of it's read-ahead caching operations.

Input:

    a STORAGE_SET_READ_AHEAD structure which contains:
        * the trigger address
        * the target address

Output:

    none
