请教filemon中IRP_MJ_READ*和IRP_MJ_WRITE*带星号是什么意思？
我在“读懂常见IRP:IRP_MJ_CLEANUP\IRP_MJ_CLOSE\IRP_MJ_CREATE”一文中看到说IRP_MJ_WRITE*是分段写入，提供Offset，每次写入65536字节，这个说法对不对呢？
谢谢！ |

filemon的帮助中有相关的解释，如下：、
On Windows NT/2K there is a special file name, DASD (Direct Access Storage Device), that is used to indicate file I/O that is bypassing file system structures and directly effecting data on the logical partition, or I/O that is targeted at file system-internal unnamed data streams. Unnamed data streams are used to represent file system metadata files such as the File Allocation Table in the FAT file system, or the Master File Table (MFT) in NTFS. Also on Windows NT/2K, an asterisk （*） following an IRP_MJ_READ or IRP_MJ_WRITE indicates paging I/O. 是分页读/写请求. |
