旧文件系统筛选器驱动程序可以使用 FSRTL_PER_FILE_CONTEXT 结构将特定于驱动程序的上下文信息关联到打开的文件。语法C++ 复制 typedef struct _FSRTL_PER_FILE_CONTEXT { LIST_ENTRY Links; PVOID OwnerId; PVOID InstanceId; PFREE_FUNCTION FreeCallback; } FSRTL_PER_FILE_CONTEXT, *PFSRTL_PER_FILE_...
FSRTL_PER_FILEOBJECT_CONTEXT结构可以从分页池或非页池进行分配,并且必须使用 FsRtlInitPerFileObjectContext 宏进行初始化。若要将FSRTL_PER_FILEOBJECT_CONTEXT结构或筛选器定义的每文件对象上下文结构(包含初始化FSRTL_PER_FILEOBJECT_CONTEXT结构)插入文件对象的所有上下文结构列表中,请使用 FsRtlInsertPerFile...
