Enumerates the advisory connections registered for an object, so a container
can know what to release prior to closing down.
| IEnumSTATDATA **ppenumAdvise
||//Pointer to storage of a struct
[out] Points to where the new enumerator should be returned. NULL is a legal
return value, indicating that the object does not have any advisory connections.
If an error is returned, this parameter must be set to NULL. Each time an
object receives a call to EnumAdvise
, it must increase the reference count on the pointer it returns. It is the
caller's responsibility to call Release when it is done with the pointer.
Enumerator returned successfully.
Unspecified error encountered.
is not implemented.
method provides a way for containers to keep track of advisory connections
registered for their objects. A container normally would call this function so
that it can instruct an object to release each of its advisory connections prior
to closing down.
enumerates items of type STATDATA
. Upon receiving the pointer, the container can then loop through STATDATA
and call IOleObject::Unadvise
for each enumerated connection.
The usual way to implement this function is to delegate the call to the IOleAdviseHolder
interface. Only the pAdvise
members of STATDATA
are relevant for IOleObject::EnumAdvise
