AACS_READ_BINDING_NONCE structure (ntddcdvd.h)
The AACS_READ_BINDING_NONCE structure is a wrapper for the Authentication Grant Identifier (AGID) and logical block address (LBA)/length pair that are required to read a nonce.
Syntax
typedef struct _AACS_READ_BINDING_NONCE {
DVD_SESSION_ID SessionId;
ULONG NumberOfSectors;
ULONGLONG StartLba;
union {
HANDLE Handle;
ULONGLONG ForceStructureLengthToMatch64bit;
};
} AACS_READ_BINDING_NONCE, *PAACS_READ_BINDING_NONCE;
Members
SessionId
A value of type DVD_SESSION_ID that specifies an AGID. The client obtains this value by a successful call to IOCTL_AACS_START_SESSION.
NumberOfSectors
The number of sectors in the area for which the binding nonce is retrieved. To request the nonce for a file, the caller of IOCTL_AACS_READ_BINDING_NONCE must set this member to MAXULONGLONG.
StartLba
The starting logical block address of the area for which the binding nonce is retrieved. To request the nonce for a file, the caller of IOCTL_AACS_GENERATE_BINDING_NONCE or IOCTL_AACS_READ_BINDING_NONCE must set this member to MAXULONGLONG.
Handle
The file handle. Callers of IOCTL_AACS_READ_BINDING_NONCE that use file system support can set this member to a file handle. If the caller does not use file system support, this member must have a value of INVALID_HANDLE_VALUE.
ForceStructureLengthToMatch64bit
Remarks
Clients retrieve the binding nonce with an IOCTL_AACS_GENERATE_BINDING_NONCE request or an IOCTL_AACS_READ_BINDING_NONCE request.
