Get derived extent by position
DBExtend * DBExtend :: GetDerivedExtent ( int16 extent_pos )
This implementation searches for the extent in the extent list at the position in the list. This function can be used to list all derived extents for an extent. The function returns NULL, when no (more) extents could be found at the given position.
- extent_pos
- Extent position in the list
This is the relative position of an extent in a list. The first extent in the list has position 0.
