Parallels C API Reference Guide
Enables or disables notification of automatic snapshot creation, a SmartGuard feature.
SmartGuard is a facility that allows to make automatic snapshots of a virtual machine at predefined time intervals. By default, the snapshots are creating transparently to the user. If needed, Parallels Service can notify the user that a snapshot is about to be created. The user can then choose to proceed with snapshot creation or cancel it. This function allows to enabled or disable this feature. The notifications are received by the client via the PHT_EVENT handle received by a callback function. See PHT_EVENT and PrlEvent_CreateAnswerEvent for more information and code samples.
