STATSTG structure (objidl.h)

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

Syntax

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

Members

pwcsName

A pointer to a NULL-terminated Unicode string that contains the name. Space for this string is allocated by the method called and freed by the caller (for more information, see CoTaskMemFree). To not return this member, specify the STATFLAG_NONAME value when you call a method that returns a STATSTG structure, except for calls to IEnumSTATSTG::Next, which provides no way to specify this value.

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.

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. For more information about the values available, see the LOCKTYPE enumeration. 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.

reserved

Reserved for future use.
