STATSTG - OLE Programmer's Reference (ole.hlp)

STATSTG

The STATSTG structure contains statistical information about an open storage, stream, or byte array object. This structure is used in the IEnumSTATSTG, ILockBytes, IStorage, and IStream interfaces.

Defined in the IStream interface (stream.idl).

typedef struct tagSTATSTG
{
LPWSTR pwcsName;
DWORD type;
ULARGE_INTEGER cbSize;
FILETIME mtime;
FILETIME ctime;
FILETIME atime;
DWORD grfMode;
DWORD grfLocksSupported;
CLSID clsid;
DWORD grfStateBits;
DWORD dwStgFmt;
} STATSTG;

Members
pwcsName
Points to a NULL-terminated string containing the name. Space for this string is allocated by the method called and freed by the caller. You can specify not to return this member by specifying the STATFLAG_NONAME value when you call a method that returns a STATSTG structure.

type
Indicates the type of storage object. This is one of the values from the STGTY enumeration.

cbSize
Specifies the size in bytes of the stream or byte array. Undefined for storage objects; zero is returned for storage objects.

mtime
Indicates the last modification time for this storage, stream, or byte array.

ctime
Indicates the creation time for this storage, stream, or byte array.

atime
Indicates the last access time for this storage, stream or byte array.

grfMode
Indicates the access mode specified when the object was opened. This member is only valid in calls to Stat methods.

grfLocksSupported
Indicates the types of region locking supported by the stream or byte array. See the LOCKTYPES enumeration for the values available. This member is not used for storage objects.

clsid
Indicates the class identifier for the storage object; set to CLSID_NULL for new storage objects. This member is not used for streams or byte arrays.

grfStateBits
Indicates the current state bits of the storage object, that is, the value most recently set by the IStorage::SetStateBits method. This member is not valid for streams or byte arrays.

dwStgFmt

Indicates the format of the storage object. This is one of the values from the STGFMT enumeration.
