A driver can use IOCTL_STORAGE_QUERY_PROPERTY to return properties of a storage device or adapter. The request indicates the kind of information to retrieve, such as inquiry data for a device or capabilities and limitations of an adapter. IOCTL_STORAGE_QUERY_PROPERTY can also be ...
透過lpOutBuffer參數傳回的選擇性輸出緩衝區可以是數個結構之一,視lpInBuffer參數所指向之STORAGE_PROPERTY_QUERY結構的PropertyId成員值而定。 這些值是由STORAGE_PROPERTY_ID列舉所列舉。 如果STORAGE_PROPERTY_QUERY的QueryType成員設定為PropertyExistsQuery,則不會傳回任何結構。

驱动程序可以使用IOCTL_STORAGE_QUERY_PROPERTY返回存储设备或适配器的属性。 请求指示要检索的信息类型,例如设备的查询数据或适配器的功能和限制。 IOCTL_STORAGE_QUERY_PROPERTY 还可用于确定端口驱动程序是否支持特定的属性,或者可以使用后续更改属性请求修改属性描述符中的哪些字段。

通过lpOutBuffer参数返回的可选输出缓冲区可以是多个结构之一,具体取决于lpInBuffer参数指向的STORAGE_PROPERTY_QUERY结构的PropertyId成员的值。 这些值由STORAGE_PROPERTY_ID枚举进行枚举。 如果STORAGE_PROPERTY_QUERY的QueryType成员设置为PropertyExistsQuery,则不返回任何结构。
