Note

This method is unsupported in Windows Embedded CE 6.0.

This 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 IRTCClientProvisioning2::EnableProfileEx method, the newly created watcher is persisted on the server.

Syntax

HRESULT AddWatcherEx( 
  BSTR bstrPresentityURI, 
  BSTR bstrUserName, 
  BSTR bstrData,
  RTC_WATCHER_STATE enState, 
  VARIANT_BOOL fPersistent, 
  RTC_ACE_SCOPE enScope, 
  IRTCProfile* pProfile, 
  long lFlags, 
  IRTCWatcher2** ppWatcher 
);

Parameters

  • bstrPresentityURI
    [in] The SIP URI of the new watcher.

    The sip: prefix is optional when providing the URI.

  • bstrUserName
    [in] The display name of the new watcher.
  • bstrData
    [in] Optional string value used as a private data BLOB.
  • enState
    [in] RTC_WATCHER_STATE enumeration value specifying the initial watcher state.

  • fPersistent
    [in] VARIANT_TRUE if the watcher should be saved in persistent storage.

    VARIANT_FALSE if the watcher is volatile and will be lost when the RTC client process terminates.

  • enScope
    [in] RTC_ACE_SCOPE enumeration value specifying the specific the scope of the new watcher's access control entry (ACE).

  • pProfile
    [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.

  • lFlags
    [in] Reserved. This value must be set to zero.

  • ppWatcher
    [out] Pointer to an IRTCWatcher2 interface.

    This parameter can be NULL, indicating that the method should not retrieve an interface.

    This method adds a reference to the Watcher object, which the caller is responsible for releasing.

Return Value

This method can return an RTC_E_ constant.

The following table shows additional possible return values.
