Virtuozzo Virtualization SDK C API Reference
Allows to grant or deny a permission to new users to modify Virtuozzo Service preferences.
By default, only administrators of the host OS can modify Virtuozzo Service preferences. When a new Virtuozzo Service user profile is created (this happens when a user logs on to the Virtuozzo Service for the first time), he/she will be granted or denied this privilege based on the default setting. This function allows to set that default setting. To determine the current behavior, use PrlDispCfg_CanChangeDefaultSettings. Please note that this function only affects the new users (the users that will be created in the future). The profiles of the existing users will not (and cannot) be modified.
