StartingVcn是FSCTL_GET_RETRIEVAL_POINTERS开始枚举盘区以及关联的虚拟和逻辑群集号的 VCN。 使用文件系统控制代码FSCTL_GET_RETRIEVAL_POINTERS首次调用FltFsControlFile或ZwFsControlFile时,StartingVcn应设置为零。 如果OutputBuffer的大小不足以容纳文件的 VPN 和盘区的完整映射,则调用方必须使用在 RETRIEVAL_POINTERS_...
The FSCTL_GET_RETRIEVAL_POINTERS reply message returns the results of the FSCTL_GET_RETRIEVAL_POINTERS request as a variably sized data element, RETRIEVAL_POINTERS_BUFFER, that specifies the allocation and location on disk of a specific file. The FSCTL_GET_RETRIEVAL_POINTERS reply returns...

As for the buffer-size relational information, which is the specific variable storing the size of the buffer pointed by the pointers, it is tough to analyze by traditional methods. Moreover, we observe that most methods are designed for specific information. To address these limitations, we ...
Additional pointers have been added to the tree. For example, each leaf page may have references to its sibling pages to the left and right, which allows scanning keys in order without jumping back to parent pages. Comparing B-Trees and LSM-Trees ...
(VVBN) space and may maintain metadata, such as block allocation bitmap structures, within that PVBN space. PVBNs may be used as block pointers within buffer trees of files stored in a virtual volume. Systems and methods for creating or using PVBNs are described in further detail in U.S...
In one example, a bot proxy owner 2680A may be configured to receive a list of bots expected to perform respective tasks and any other suitable information (e.g. storage structure map, pointers to level manager interfaces and objects, etc.) for the operation of the bot proxy owner 2680A....
