SCSISCAN_CMD structure (scsiscan.h)

  • Article

The SCSISCAN_CMD structure is used as a parameter to DeviceIoControl, when the specified I/O control code is IOCTL_SCSISCAN_CMD.

Syntax

typedef struct _SCSISCAN_CMD {
  ULONG  Reserved1;
  ULONG  Size;
  ULONG  SrbFlags;
  UCHAR  CdbLength;
  UCHAR  SenseLength;
  UCHAR  Reserved2;
  UCHAR  Reserved3;
  ULONG  TransferLength;
  UCHAR  Cdb[16];
  PUCHAR pSrbStatus;
  PUCHAR pSenseBuffer;
} SCSISCAN_CMD, *PSCSISCAN_CMD;

Members

Reserved1

Reserved. Do not use.

Size

Caller-supplied size, in bytes, of the SCSISCAN_CMD structure.

SrbFlags

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

CdbLength

Length, in bytes, of the CDB contained in the Cdb member.

SenseLength

Length, in bytes, of the sense buffer the pSenseBuffer member points to.

Reserved2

Reserved. Do not use.

Reserved3

Reserved. Do not use.

TransferLength

Length, in bytes, of the buffer to be transferred. This should match the value specified for the DeviceIoControl function's nOutBufferSize parameter.

Cdb[16]

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

pSrbStatus

Caller-supplied pointer that will receive one of the SRB_STATUS-prefixed status values defined in srb.h.

pSenseBuffer

Caller-supplied pointer to a request-sense buffer, to be filled in by the kernel-mode driver.
