IWMSPushSource::PausePushing

The PausePushing method is called by the server to pause the flow of packets down a data path.

Syntax

Parameters

pCommand

[in] Pointer to an IWMSCommandContext interface containing the context associated with this call.

pCallback

[in] Pointer to an IWMSPushSourceCallback interface used to report the status of this method call.

qwContext

[in] QWORD containing a value defined by the server to identify which call to PausePushing the plug-in is responding to when it calls IWMSPushSourceCallback::OnPausePushing. You must pass this value back unaltered when you call OnPausePushing.

Return Values

If the method succeeds, the plug-in must return S_OK. To report an error, the plug-in can return any HRESULT other than S_OK. If the plug-in uses the IWMSEventLog interface to log error information directly to the Windows Event Viewer, it is recommended that it return NS_E_PLUGIN_ERROR_REPORTED. Typically, the server attempts to make plug-in error information available to the server object model, the Windows Event Viewer, and the troubleshooting list in the details pane of the Windows Media Services MMC. However, if the plug-in uses the IWMSEventLog interface to send custom error information to the Windows Event Viewer, returning NS_E_PLUGIN_ERROR_REPORTED stops the server from also logging to the event viewer. For more information about retrieving plug-in error information, see Identifying Plug-in Errors.
