IStorage::DestroyElement

Removes the specified storage or stream from this storage object.

HRESULT DestroyElement(
  wchar * pwcsName  //Points to the name of the element to be removed
);

Parameter

pwcsName: [in] Points to a wide character string that contains the name of the storage or stream to be removed.

Return Values

S_OK: The element was successfully removed.
E_PENDING: Asynchronous Storage only: Part or all of the element's data is currently unavailable. For more information see IFillLockBytes and Asynchronous Storage.
STG_E_ACCESSDENIED: The caller does not have sufficient permissions for removing the element.
STG_E_FILENOTFOUND: The element with the specified name does not exist.
STG_E_INSUFFICIENTMEMORY: The element was not removed due to a lack of memory.
STG_E_INVALIDNAME: Invalid value for pwcsName.
STG_E_INVALIDPOINTER: The pointer specified for the element was invalid.
STG_E_INVALIDPARAMETER: One of the parameters was invalid.
STG_E_REVERTED: The storage object has been invalidated by a revert operation above it in the transaction tree.
STG_E_TOOMANYOPENFILES: The element was not removed because there are too many open files.

Remarks

The DestroyElement method deletes a substorage or stream from the current storage object. After a successful call to DestroyElement, any open instance of the destroyed element from the parent storage becomes invalid.

If a storage object is opened in transacted mode, destruction of an element requires that the call to DestroyElement be followed by a call to IStorage::Commit.
