Re: Current Process

I'm trying to find away to dump some info to a file from within a driver,
I know this isn't a good idea in general, but it's the best way to go
about it in my situation because I don't want to have another user process
to do it for me. The method I'm trying is something that was sugested on
one of the darwin lists (don't remember which one or when). The person
sugested calling the entry point for the open syscall and the writing to
the file with the entry point for the write syscall. These entry points
require a struct proc * to be passed in. Is there another way my KEXT can
get output to a file that isn't system.log?
