IUPnPReregistrar::ReregisterRunningDevice method (upnphost.h)

  • Article

The ReregisterRunningDevice method re-registers a running device with the device host. The device information is stored by the device host. Then, the device host returns a device identifier and publishes and announces the device on the network. The publication of this device does not persist across system boots.

Syntax

HRESULT ReregisterRunningDevice(
  [in] BSTR     bstrDeviceIdentifier,
  [in] BSTR     bstrXMLDesc,
  [in] IUnknown *punkDeviceControl,
  [in] BSTR     bstrInitString,
  [in] BSTR     bstrResourcePath,
  [in] long     nLifeTime
);

Parameters

[in] bstrDeviceIdentifier

Specifies the device identifier of the device. This must be the same identifier returned by IUPnPRegistrar::RegisterRunningDevice in the pbstrDeviceIdentifier parameter.

[in] bstrXMLDesc

Specifies the XML device description template of the device to register.

[in] punkDeviceControl

Specifies the IUnknown pointer to the device's device control object.

[in] bstrInitString

Identifies the initialization string specific to the device. This string is later passed to IUPnPDeviceControl::Initialize.

[in] bstrResourcePath

Specifies the location of the resource directory of the device. This resource directory contains the icon files and service descriptions that are specified in the device description template bstrXMLDesc.

[in] nLifeTime

Specifies the lifetime of the device announcement, in seconds. After the timeout expires, the announcements are refreshed. If you specify zero, the default value of 1800 (30 minutes) is used. The minimum allowable value is 900 (15 minutes); if you specify anything less than 900, an error is returned.

Return value

If the method succeeds, the return value is S_OK. Otherwise, the method returns one of the COM error codes defined in WinError.h, or one of the following UPnP-specific error codes.

Return code Description
UPNP_E_DEVICE_NOTREGISTERED

UPNP_E_DUPLICATE_SERVICE_ID
 A duplicate service ID for a service within the same parent device exists.
UPNP_E_INVALID_DESCRIPTION
