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? -Joey On Tue, 10 Jun 2003, Justin C. Walker wrote:

How can I get the current process from inside a kernel extension? I've

load becuase of unresolved symbols.
The call is current_proc_EXTERNAL(), which gets you a 'struct proc *'.
You have to be *very* careful in using the result; check for NULL, and
make sure that you fully understand the context in which your driver is
running when you call it. Getting the identity of the current process
at random points in your driver's execution path may give you an
equally random process.
What are you trying to do?
