hello everybody:
I’m a new comer and I’m studying how to write file system filter driver now.It’s rather hard to me.I hope I can get help from you.
I’m testing R. Nagar’s sample filter driver “sfilter”.It works properly in one Win XP computer.But in another Win2000 computer something seems wrong with it.I use SoftIce to debug the driver and set a breakpoint on the begining of the function “SFilterFSDNotification”,which was passed to the function “IoRegisterFsRegistrationChange” as the secnond paramete.In the XP computer,after sfilter was loaded,it does jump to the breakpoint if a new volume is mounted,as the IFS DDK says.But under Win2000 it doesn’t arrive to the breakpoint at all.I don’t know why.I hope u can tell me the reason.thanks very much!
Best Regards.
Jim
