Interface ExtentCommitI

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

    Type

         extent_hooks_t *extent_hooks,
         void *addr,
         size_t size,
         size_t offset,
         size_t length,
         unsigned int arena_ind

        Extent commit hook.

        An extent commit function conforms to the extent_commit_t type and commits zeroed physical memory to back pages within an extent at given addr and size at offset bytes, extending for length on behalf of arena arena_ind, returning false upon success. Committed memory may be committed in absolute terms as on a system that does not overcommit, or in implicit terms as on a system that overcommits and satisfies physical memory needs on demand via soft page faults. If the function returns true, this indicates insufficient physical memory to satisfy the request.
