matrox meteor framegrabber and qnx

I have an old matrox meteor and I want to use tihs under qnx.
I have a driver to acquire video under qnx4. This river is a ripp-off of the
linux driver. . I read that it access to /dev/shmem/Physical, so I
believe that other entry in /dev (like mmetfgrab0) are useless.
1 - after successfully compile, I don t know how to use it, trying to
access to /dev/mmetfgrab0 ~or something like this~
2 - I hadn’t mknod to create entry in /dev like the linux version
3 - to resume, I don t know how I can use it?

any help would be really valuable. thx in advance.
