Filtering All Paging File I/O Under Windows 95Last reviewed: August 13, 1997Article ID: Q141204 |
The information in this article applies to:
SUMMARYA file system API hook installed by a VxD by calling IFSMGR_InstallFileSystemAPIHook will not see initial file I/O requests for the paging file unless it installs the hook during Device_Init.
MORE INFORMATIONSome file system API hooker VxDs need to see all file I/O, including all the initial requests for the paging file used by Windows. The FS_ReadFile and FS_WriteFile requests will be sent for the paging file with the R0_SWAPPER_CALL flag set for paging file I/O. The paging file is opened at the Init_Complete system control message sent to VxDs. If the VxD installs the hook during Device_Init, it will see all paging file I/O requests.Keywords : kbhowto kbprg Version : 4.0 Platform : WINDOWS Issue type : kbhowto |
