Enumerates objects in the current container.
Syntax
HRESULT EnumObjects( DWORD grfFlags, //Value specifying what is to be enumerated IEnumUnknown **ppenum //Address of output variable that receives the ); // IEnumUnknown interface pointer |
Parameters
- grfFlags
-
[in] Value that specifies which objects in a container are to be enumerated, as defined in the enumeration OLECONTF.
- ppenum
-
[out] Address of IEnumUnknown* pointer variable that receives the interface pointer to the enumerator object. Each time a container receives a successful call to EnumObjects, it must increase the reference count on the * ppenumpointer the method returns. It is the caller's responsibility to call IUnknown::Releasewhen it is done with the pointer. If an error is returned, the implementation must set * ppenumto NULL.
Return Value
This method supports the standard return value E_FAIL, as well as the following:
Value | Description |
---|---|
S_OK |
Enumerator successfully returned. |
E_NOTIMPL |
Object enumeration not supported. |
Remarks
A container should implement EnumObjectsto enable programmatic clients to find out what objects it holds. This method, however, is not called in standard linking scenarios.
