Interface ExtentMergeI

  • All Superinterfaces:
    org.lwjgl.system.CallbackI, org.lwjgl.system.Pointer
    All Known Implementing Classes:
    ExtentMerge
    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 ExtentMergeI
    extends org.lwjgl.system.CallbackI
    Instances of this interface may be set to the ExtentHooks struct.

        Extent merge hook.

        An extent merge function conforms to the extent_merge_t type and optionally merges adjacent extents, at given addr_a and size_a with given addr_b and size_b into one contiguous extent, operating on committed/decommitted memory as indicated, on behalf of arena arena_ind, returning false upon success. If the function returns true, this indicates that the extents remain distinct mappings and therefore should continue to be operated on independently.
