Re: Getting a hook from shell mode to do motion detection?

Yes, I just got  sample-trigger-capture.c and context.c to build by
adding a couple missing headers (unistd.h and sys/types.h for lseek).

I get it, these are just snippets, but what I was hoping to do was
work from a working program.  Maybe I can do that now.
