IWMSPlaylistParserPlugin.CreatePlaylistParser (C#)
The CreatePlaylistParser method creates an IWMSPlaylistParserIWMSPlaylistParser Object (C#) for use by the plug-in.
void IWMSPlaylistParserPlugin.CreatePlaylistParser(
IWMSCommandContext pCommandContext,
IWMSContext pUser,
IWMSContext pPresentation,
uint dwFlags,
IWMSClassObject pFactory,
IWMSBufferAllocator pBufferAllocator,
IWMSPlaylistParserPluginCallback pCallback,
ulong qwContext
);
Arguments
IWMSCommandContextIWMSCommandContext Object (C#) specifying the request command context that is passed in by the server. |
|
IWMSContextIWMSContext Object (C#) specifying the user context that is passed in by the server. |
|
IWMSContext object specifying the presentation context that is passed in by the server. |
|
Reserved for future use. |
|
IWMSClassObjectIWMSClassObject Object (C#) implemented by the server, that can be used as a class factory to create the other objects. |
|
IWMSBufferAllocatorIWMSBufferAllocator Object (C#) to be used to allocate a buffer for reading and writing. |
|
IWMSPlaylistParserPluginCallbackIWMSPlaylistParserPluginCallback Object (C#) that is used by the plug-in to report to the server the result of the object creation process. |
|
ulong containing a value defined by the server to identify which call to CreatePlaylistParser the plug-in is responding to when it calls IWMSPlaylistParserPluginCallback.OnCreatePlaylistParser. You must pass this value back unaltered when you call OnCreatePlaylistParser. |
Return Value
This method does not return a value. To report an error, the plug-in can throw a COMException object to the server. If the plug-in uses the IWMSEventLogIWMSEventLog Object (C#) to log error information, it is recommended that it throw NS_E_PLUGIN_ERROR_REPORTED (0xC00D157D). 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 object to send custom error information to the Windows Event Viewer, throwing NS_E_PLUGIN_ERROR_REPORTED stops the server from also logging to the event viewer. For more information about plug-in error information, see Identifying Plug-in Errors.
Remarks
This method is implemented by the plug-in and called by the server.
