Syntax
HRESULT Stat( STATSTG * pstatstg, DWORD grfStartFlag );
Parameters
pstatstg
[out] Pointer to a STATSTG structure where this method places information about this stream object. This pointer is NULL if an error occurs.
grfStatFlag
[in] Specifies that this method does not return some of the members in the STATSTG structure, thus saving a memory allocation operation. Values are taken from the STATFLAG enumeration.
Return Value
One of the values described in the following table is returned.
| Value | Description |
| S_OK | The STATSTG structure was successfully returned at the specified location. |
| E_PENDING | Asynchronous Storage only: Part or all of the stream’s data is currently unavailable. |
| STG_E_ACCESSDENIED | The caller does not have sufficient permissions for accessing statistics for this storage object. |
| STG_E_INSUFFICIENTMEMORY | The STATSTG structure was not returned due to a lack of memory. |
| STG_E_INVALIDFLAG | The value for the grfStateFlag parameter is not valid. |
| STG_E_INVALIDPOINTER | The pStatStg pointer is not valid. |
| STG_E_REVERTED | The object has been invalidated by a revert operation above it in the transaction tree. |
Remarks
IStream::Stat retrieves a pointer to the STATSTG structure that contains information about this open stream. When this stream is within a structured storage and IStorage::EnumElements is called, it creates an enumerator object with the IEnumSTATSTG interface on it, which can be called to enumerate the storages and streams through the STATSTG structures associated with each of them.
