Hello. Would it be possible to port the sendfile system call to a =
FreeBSD 2.2 based system? Has anyone done this? I am trying to port the =
code from a later FreeBSD release and I have been unable to find out =
what the VOP_GETVOBJECT() macro does and how/what should it be replaced =
with for my case. Any help is appreciated.

Thanks
