)


This function returns the number of bytes of roll 'file' which would be
passed to the Frustrum if a partition mark were to be set in the given
partition. This is so that an application can ensure that enough space is
available before setting the mark.


Specific Errors:
    PK_ERROR_rollback_not_started  Partitioned rollback is not active


This function should only be called when partitioned rollback has been started
with PK_DELTA_register_callbacks.
