Interface MDBRelFuncI

  • All Superinterfaces:

    All Known Implementing Classes:
    MDBRelFunc

    @FunctionalInterface
public interface MDBRelFuncI
extends org.lwjgl.system.CallbackI.V
    A callback function used to relocate a position-dependent data item in a fixed-address database.

    The newptr gives the item's desired address in the memory map, and oldptr gives its previous address. The item's actual data resides at the address in item. This callback is expected to walk through the fields of the record in item and modify any values based at the oldptr address to be relative to the newptr address.
