java.lang.Object

org.lwjgl.system.Callback

public abstract class MDBRelFunc
extends org.lwjgl.system.Callback
implements MDBRelFuncI

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.

Type

 void (*) (
     MDB_val *item,
     void *oldptr,
     void *newptr,
     void *relctx
 )
