  RAW_SCSI_VIRTUAL_DISK_VERSION Version;
  union {
    struct {
      BOOL  RSVDHandle;
      UCHAR DataIn;

Members

Version

A RAW_SCSI_VIRTUAL_DISK_VERSION enumeration that specifies the version of the RAW_SCSI_VIRTUAL_DISK_PARAMETERS structure being passed to or from the VHD functions.

Version1

A structure with the following members.

Version1.RSVDHandle

If TRUE, indicates the operation will be transported to the virtual disk using the RSVD protocol.

Version1.DataIn

If TRUE, indicates the SCSI command will read data from the DataBuffer. If FALSE, indicates data may be written.

Version1.CdbLength

Length, in bytes, of the command descriptor block (CDB) contained in the CDB member.

Version1.SenseInfoLength

Length, in bytes, of the sense buffer.

Version1.SrbFlags

Caller-supplied SRB_FLAGS-prefixed bit flag specifying the requested operation. Flags are defined in srb.h.

Version1.DataTransferLength

Length, in bytes, of the buffer to be transferred.

Version1.DataBuffer

A pointer to the SCSI data buffer.

Version1.SenseInfo

A pointer to a buffer to receive SCSI sense info after completion of the command.

Version1.Cdb

Caller-supplied CDB data. (The CDB structure is declared in scsi.h.)
