STORAGE_PROPERTY_QUERY structure

Indicates the properties of a storage device or adapter to retrieve as the input buffer passed to the IOCTL_STORAGE_QUERY_PROPERTY control code.

Syntax


typedef struct _STORAGE_PROPERTY_QUERY {
  STORAGE_PROPERTY_ID PropertyId;
  STORAGE_QUERY_TYPE  QueryType;
  BYTE                AdditionalParameters[1];
} STORAGE_PROPERTY_QUERY, *PSTORAGE_PROPERTY_QUERY;

Members

PropertyId

Indicates whether the caller is requesting a device descriptor, an adapter descriptor, a write cache property, a device unique ID (DUID), or the device identifiers provided in the device's SCSI vital product data (VPD) page. For a list of the property IDs that can be assigned to this member, see STORAGE_PROPERTY_ID.

QueryType

Contains flags indicating the type of query to be performed as enumerated by the STORAGE_QUERY_TYPE enumeration.

ValueMeaning
PropertyStandardQuery
0

Instructs the port driver to report a device descriptor, an adapter descriptor or a unique hardware device ID (DUID).

PropertyExistsQuery
1

Instructs the port driver to report whether the descriptor is supported.

 

AdditionalParameters

Contains an array of bytes that can be used to retrieve additional parameters for specific queries.

Remarks

The optional output buffer returned through the lpOutBuffer parameter of the IOCTL_STORAGE_QUERY_PROPERTY control code can be one of several structures depending on the value of the PropertyId member. If the QueryType member is set to PropertyExistsQuery, then no structure is returned.
