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.
