IPrintAsyncNotifyCallback interface (prnasnot.h)
Creates and manages a communication channel used by applications and components that are hosted by the print spooler.
Inheritance
The IPrintAsyncNotifyCallback interface inherits from the IUnknown interface. IPrintAsyncNotifyCallback also has these types of members:
Methods
The IPrintAsyncNotifyCallback interface has these methods.
| IPrintAsyncNotifyCallback::ChannelClosed Advises one member of a communication channel to notify the other member that the channel is being closed. |
| IPrintAsyncNotifyCallback::OnEventNotify Alerts a listener that a notification is available on a specified channel. This method is called by the print system. |
Remarks
For an application to receive notifications from a Print Spooler-hosted component, it must provide an IPrintAsyncNotifyCallback object when it registers for notifications.
A Print Spooler-hosted component that opens a bidirectional communication channel with a listening application must provide an IPrintAsyncNotifyCallback object.
