STORAGE_PROPERTY_QUERY structure (winioctl.h)
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.
AdditionalParameters[1]
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.
