Interface ExtentSplitI

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

    Type

                       int arena_ind)
        Extent split hook.

        An extent split function conforms to the extent_split_t type and optionally splits an extent at given addr and size into two adjacent extents, the first of size_a bytes, and the second of size_b bytes, 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 extent remains unsplit and therefore should continue to be operated on as a whole.
