Hi All,

Currently i am using MSVAD(simple), I want to write custom API's(from
application) which will call CopyTo() and CopyFrom() calls inside MSVAD.

Currently winmm library calls like, WaveOut or WaveIn call Copyto and
copyfrom().

Can i use IOCTL calls to do this? I believe we cant do this because of
KERNEL Streaming calls instead of IOCTL... right?
If so what is a better way to make custom calls to MSVAD driver??

Can we intercept KS calls and redirect it to other API's inside MSVAD?

Thank you a lot in advance.
