Pending Device IOCTL request

NTFSD
1

Hi All,

I am developing a file system filter driver, and there will be an
application which communicates to the filter driver Device object, not the
actual filtering device object, when I send an IOCTL from the application I
am receiving it as the fastiodevicecontrol() so is it possible to pend it
like normal IRP.

Is it not possible to force I/O manager to send IOCTL as normal IRPs.

Any information is helpful.

Thanks,
Kedar.

Return FALSE from FastIoDeviceControl to make I/O Manager send an
IRP_MJ_DEVICE_CONTROL IRP to your device.

If you return false from your fast io routine, the I/O mgr will issue the
request via the Irp dispatch function.
