IStorage::Stat (Windows Embedded CE 6.0)

  • [アーティクル]

1/6/2010

This method retrieves the STATSTG structure for this open storage object.

Syntax

HRESULT Stat( 
  STATSTG* pstatstg, 
  DWORD grfStatFlag 
);

Parameters

  • pstatstg
    [out] On return, pointer to a STATSTG structure where this method places information about the open storage object.

    This parameter is NULL if an error occurs.

  • grfStatFlag
    [in] Value that specifies that some of the members in the STATSTG structure are not returned. This saves a memory allocation operation.

    Values are taken from the STATFLAG enumeration.

Return Value

The following table shows the return values for this method.

Value Description

S_OK

The STATSTG structure was successfully returned at the specified location.

E_PENDING

Asynchronous Storage only: Part or all of the storage's data is currently unavailable.

For more information see the IFillLockBytes interface and Asynchronous Storage.

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_INVALIDPARAMETER

One of the parameters was invalid.

Remarks

IStorage::Stat retrieves the STATSTG structure for the current storage. This structure contains statistical information about the storage.

The IStorage::EnumElements method creates an enumerator object with the IEnumSTATSTG interface, though which you can enumerate the substorages and streams of a storage through the STATSTG structure of each.

To determine whether the platform supports this interface, see Determining Supported COM APIs.

Requirements

Header objidl.h, objidl.idl
Library ole32.lib, uuid.lib
Windows Embedded CE Windows CE 2.0 and later
