Let me begin by telling you a little story. Some time ago I needed to run a script at work once a day. We had tons of machines ranging from big Unix servers to Linux desktops. Due to various reasons the script could only be run on a desktop machine. However using cron was disabled on desktops. All other machines allowed cron.

Indeed that seems really insane.
That could be more portable (hmmm) than using /proc.
In BeOS the loaded images are walkable with get_next_image_info(), the first one being the exe, and it contains the full path to it. I use that trick quite often.

Also, but I consider this a bug (also because get_next_image_info() could do it) argv[0] is overwritten in BeOS by the full path to the exe, to allow the BApplication object to find its resources.
So at the question where am I, you could just say dirname(argv[0]). But of course that can't work in Unix because they use argv[0] to stuff ugly things like "-sh" for a login shell.
Hmm anyone ever thought about trying to run lsof|grep something to find the path for the mmap()ed lib ?
