    Is there anyone out there using the 32-bit Device Helper functions using
Steve Mastrianni's C-Callable Devcie Helper Library? I am writing an OS/2
2.0 character device driver, using this library to access the Device Helper
Functions. For IOCtl calls, instead of doing a LockSeg which 
locks up a whole segment in memory ( my parameter buffers are only about 15 
bytes in size , I am trying to convert the virtual memory to linear
memory using the device helper function 'VirtToLin' and then do a 'VmLock'
to lock down a page in memory. The 'VirtToLin' call seems to be going through
alright but VMLock' is failing (returns a value of 1 in ax) altho I think I am
doing the right setting up. If anyone happens to be doing this sort of stuff
I would really appreciate it if you could mail me a small sample code of how the
parameters need declared and initialized (for VMLock). My email address is
ramdas@eagle.natinst.com.

    Thanks a lot
