Virtuozzo Virtualization SDK C API Reference
Returns the numeric identifier of the package that caused the event.
The numeric identifier is a monotonically increasing number. It is reset to one on dispatcher restart. If event or job was not originated in the dispatcher, then the numeric identifier is equal to zero. A triplet of values forms a unique monotonically increasing numeric identifier that could be used for event ordering. See PrlSrvInfo_GetStartTime and PrlSrvInfo_GetStartTimeMonotonic for details on how to obtain (monotonic) dispatcher start time value.
