hi,all:
Somebody may tell me that should block the fast i/o operation in the online
encrypt/decrypt minifilter driver.
But I don’t know how to do this.When the driver detect the fast i/o write
operation in the IRP_MJ_WRITE pre- routine,if the pre-write routine return
FLT_PREOP_COMPLETE to drop this operation,the app using fast i/o will report
a error,such as acdsee 6,etc.if set the IoStatus.Status = FALSE,the app
will report error “diskfull”.i want set the IoStatus as a proper return
value ,make the io manager reprocess this operation in IRP mode.what is the
proper return value to block fast i/o???
Regards!
