Property :: version - Get version number for selected instance
The function returns the version number for the instance currently selected. Since instance versions are created only in case of updates, the access version set for the property handle might be greater than the instance version returned from the selected instance. When no instance is selected, the function returns 0xFFFFFFFF.
When no instance is selected or when the property handle does not support versioning, the function throws an error
Return value: Instance version number ( uint32 )
Instance version numbers are assigned version numbers to individual instances.
