NTDEV : User memory mapping in Driver

hi all ,
While writing a unix driver i came to know that there is a way in
Unix Kernel by which i can allocate memory and map it to the user
process.The Applicantion can use this memory and then the driver can free it
when it is not needed.This is a way of communication between a driver and a
application (other than IOCTLS).
Is a similar way exists in Windows Drivers.Say for example a NDIS
Intermediate driver can allocate memory on application behalf and map it to
the application address space.(Or any other driver for that matter…).

i am sure this would be a interesting discussion.
