    • A dynamic status tree facility for providing status information about one or more systems. The facility includes a tree data structure and methods for manipulating the data structure. The facility is accessible to provider processes using a set of provider interface methods. The facility is accessible to consumer processes using a set of consumer interface methods. The tree data structure is defined by nodes stored in shared memory and attached to by way of a defined data structure made available to the provider and consumer interface methods. The nodes in the tree data structure are defined to have a control block and a variable set of export data. The export data for any one node is specified by a variable in the control block. Certain of the exported data in the tree is representable in a format selected to have one of four defined properties.
    • 用于提供关于一个或多个系统的状态信息的动态状态树设施。 该设施包括树状数据结构和操纵数据结构的方法。 使用一组提供程序接口方法,提供程序进程可以访问该设施。 消费者流程使用一组消费者接口方法可以访问该设施。 树数据结构由存储在共享存储器中的节点定义,并通过定义的数据结构附加到提供商和消费者接口方法。 树数据结构中的节点被定义为具有控制块和导出数据的变量集合。 任何一个节点的导出数据由控制块中的变量指定。 树中某些导出的数据可以以选定为具有四个定义属性之一的格式表示。

    • A data structure, method and system are provided incorporating a general purpose memory allocator and defensive heap memory manager. This provides an ability to reliably detect various types of memory errors, dynamically enable or disable memory debugging, enhance success of read and write operations using various memory verification techniques. Further, through separation of control information associated with allocated and free chunks of memory from the chunks themselves (separation of metadata from actual data), enhanced protection of vital information about the heap memory layout in general is provided. The heap memory manager uses read, write, and execute protected heap header walls and pool header walls and may, for each pool and memory block, separately use hidden front and back Memory Debug Information Areas (MDIAs) with checksums and well-known signature fields thereby enhancing overall memory management.
    • 提供了包含通用存储器分配器和防御堆存储器管理器的数据结构,方法和系统。 这提供了可靠地检测各种类型的存储器错误,动态地启用或禁用存储器调试的能力,使用各种存储器验证技术增强了读取和写入操作的成功。 此外,通过分离与分组本身的分配的和自由的存储块相关联的控制信息(元数据与实际数据的分离),提供了关于堆存储器布局的重要信息的增强保护。 堆内存管理器使用读,写和执行保护的堆标头墙和池标题墙,并且对于每个池和内存块,可以分别使用具有校验和和公知签名字段的隐藏的前端和后端内存调试信息区域(MDI) 从而增强整体内存管理。
