IOleContainer::EnumObjects
Enumerates objects in the current container.
HRESULT EnumObjects(
DWORD grfFlags,
| //Value specifying what is to be enumerated
| IEnumUnknown **ppenum
| //Ptr to storage of enumeration
| );
|
|
Parameters
grfFlags
[in] This value specifies which objects in a container are to be enumerated,
as defined in the enumeration OLECONTF.
ppenum
[out] Points to an address where the enumerator, of type IEnumUnknown, should be returned. If an error is returned, this parameter must be set to
NULL. Each time a container receives a call to EnumObjects, it must increase the reference count on the pointer the method returns. It
is the caller's responsibility to call IUnknown::Release when it is done with the pointer.
Return Values
S_OK
Enumerator successfully returned.
E_FAIL
An unspecified error occurred.
E_NOTIMPL
Object enumeration not supported.
Comments
A container should implement EnumObjects to enable programmatic clients to find out what objects it holds. This
method, however, is not called in standard linking scenarios.
