STORAGE_QUERY_TYPE enumeration (ntddstor.h)

  • Article

The STORAGE_QUERY_TYPE enumeration is used in conjunction with the IOCTL_STORAGE_QUERY_PROPERTY request to retrieve the properties of a storage device or adapter.

Syntax

typedef enum _STORAGE_QUERY_TYPE {
  PropertyStandardQuery,
  PropertyExistsQuery,
  PropertyMaskQuery,
  PropertyQueryMaxDefined
} STORAGE_QUERY_TYPE, *PSTORAGE_QUERY_TYPE;

Constants

 
PropertyStandardQuery
Instructs the port driver to report a device descriptor, an adapter descriptor or a unique hardware device ID (DUID).
PropertyExistsQuery
Instructs the port driver to report whether the descriptor is supported.
PropertyMaskQuery
Not currently supported. Do not use.
PropertyQueryMaxDefined
Specifies the upper limit of the list of query types. This is used to validate the query type.

Remarks

Caller specifies the type of query by choosing one of the enumeration values.

Caller defines the exact nature of an IOCTL_STORAGE_QUERY_PROPERTY request by specifying the query type together with the property ID. See STORAGE_PROPERTY_QUERY for an explanation of how these two values are combined to define the query.
