  • Article

This structure is used in conjunction with IOCTL_STORAGE_QUERY_PROPERTY and IOCTL_STORAGE_SET_PROPERTY to respectively return and set protocol-specific data from a storage device or adapter.

Syntax

typedef struct _STORAGE_PROTOCOL_DATA_DESCRIPTOR_EXT {
  ULONG                              Version;
  ULONG                              Size;
  STORAGE_PROTOCOL_SPECIFIC_DATA_EXT ProtocolSpecificData;
} STORAGE_PROTOCOL_DATA_DESCRIPTOR_EXT, *PSTORAGE_PROTOCOL_DATA_DESCRIPTOR_EXT;
