The AddWatcherEx method adds a new watcher rule object (access control entity). The state of the newly added watcher can be allowed, blocked, prompt, or deny. If watcher roaming is enabled by passing the RTCRET_WATCHER_ROAMING flag to the IRTCClientProvisioning::EnableProfileEx method, the newly created watcher is persisted on the server.
HRESULT AddWatcherEx(BSTRbstrPresentityURI, BSTRbstrUserName, BSTRbsatrData, RTC_WATCHER_STATEenState, VARIANT_BOOLfPersistent, RTC_ACE_SCOPEenScope, IRTCProfile*pProfile, longlFlags, IRTCWatcher2**ppWatcher);
[in] String value that contains the SIP URI of the new watcher. The "sip:" prefix is optional when providing the URI.
[in] String value that contains the display name of the new watcher.
[in] Optional string value used as a private data blob.
[in] RTC_WATCHER_STATE enumeration value used to describe the initial watcher state.
[in] Boolean value that indicates whether or not the watcher should be persisted after shutdown.
Value Meaning VARIANT_TRUE The watcher should be saved in persistent storage. VARIANT_FALSE The watcher is volatile and will be lost when the RTC Client process terminates.
[in] RTC_ACE_SCOPE enumeration value used to describe the specific scope of the new watcher's ACE.
[in] Pointer to an IRTCProfile interface that specifies a provisioning profile to associate with this watcher. If IRTCClientPresence2::EnablePresenceEx has been used to enable a presence profile, this parameter should be set to NULL.
[in] Reserved. This value should be set to zero.
[out] Pointer to an IRTCWatcher2 interface on the newly created Watcher object. This parameter may be NULL, indicating that the method should not return an interface. This call adds a reference to the watcher object, which the caller is responsible for releasing.
RTC methods may return an RTC_E_ constant.

|E_INVALIDARG||The bstrPresentityURI is NULL, or the enscope enumeration value is not valid.|
|E_POINTER||One of the pointers in the parameter list is not valid.|
