STORAGE_RPMB_DESCRIPTOR structure (ntddstor.h)
The STORAGE_RPMB_DESCRIPTOR structure contains information about a device's Replay Protected Memory Block (RPMB) support.
Syntax
typedef struct _STORAGE_RPMB_DESCRIPTOR {
ULONG Version;
ULONG Size;
ULONG SizeInBytes;
ULONG MaxReliableWriteSizeInBytes;
STORAGE_RPMB_FRAME_TYPE FrameFormat;
} STORAGE_RPMB_DESCRIPTOR, *PSTORAGE_RPMB_DESCRIPTOR;
Members
Version
Version of this structure. Set to STORAGE_RPMB_DESCRIPTOR_VERSION_1.
Size
Size of this structure, in bytes. Set to sizeof(STORAGE_RPMB_DESCRIPTOR).
SizeInBytes
Size of the RPMB, in bytes. SizeInBytes cannot be zero.
MaxReliableWriteSizeInBytes
Maximum amount of data supported in one transaction, in bytes. MaxReliableWriteSizeInBytes cannot be zero.
FrameFormat
A **STORAGE_RPMB_FRAME_TYPE structure identifying the frame format that the payload will be in.
Remarks
An application will issue IOCTL_STORAGE_QUERY_PROPERTY with the STORAGE_PROPERTY_ID enumeration set to StorageAdapterRpmbProperty to determine whether the device contains an RPMB, and the maximum payload size the RPMB supports.
Storport responds with the payload information in this structure when the STORAGE_QUERY_TYPE enumeration is set to PropertyStandardQuery.
