STORAGE_DIAGNOSTIC_MP_REQUEST structure (ntddscsi.h)
Describes a diagnostic request to Miniport. The STORAGE_DIAGNOSTIC_MP_REQUEST structure is provided in the input/output buffer of an IOCTL_SCSI_MINIPORT_DIAGNOSTIC request.
Syntax
typedef struct _STORAGE_DIAGNOSTIC_MP_REQUEST {
ULONG Version;
ULONG Size;
MP_STORAGE_DIAGNOSTIC_TARGET_TYPE TargetType;
MP_STORAGE_DIAGNOSTIC_LEVEL Level;
GUID ProviderId;
ULONG BufferSize;
ULONG Reserved;
UCHAR DataBuffer[ANYSIZE_ARRAY];
} STORAGE_DIAGNOSTIC_MP_REQUEST, *PSTORAGE_DIAGNOSTIC_MP_REQUEST;
Members
Version
Version of this structure.
Size
Specifies the whole size of the structure and the associated data buffer.
TargetType
Specifies the request target type. See definitions for STORAGE_DIAGNOSTIC_TARGET_TYPE.
Level
Specifies the Diagnostic level. See definitions for STORAGE_DIAGNOSTIC_LEVEL.
ProviderId
Specifies the GUID of the diagnostic data provider.
BufferSize
Specifies the Data buffer size. As an input buffer, BufferSize should be set to number of bytes allocated for the DataBuffer. If the request is failed because of buffer too short, BufferSize should be set to the length required for DataBuffer by the diagnostic data provider; If the request is successful, it should be filled with returned data size of DataBuffer. For other cases, it should be cleared to 0.
Reserved
Reserved for future use.
DataBuffer[ANYSIZE_ARRAY]
Specifies the Diagnostic data buffer.
