- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@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, andoldptr
gives its previous address. The item's actual data resides at the address initem
. This callback is expected to walk through the fields of the record initem
and modify any values based at theoldptr
address to be relative to thenewptr
address.Type
void (*) ( MDB_val *item, void *oldptr, void *newptr, void *relctx )
