<ghled> uh oh
<ghled> why not?
<Alipha> you could look at argv[0] and see if it has the absolute path, relative path, or just the program name on your platform
<skie> if you're executing it via the shell, the cwd is probably going to be the same as the directory you were in when you executed the program
<sculptor> ghled - can't you use relative address?
<skie> I'm 90% sure that cwd is one of the things thats copied with fork
<ghled> sculptor, I don't think that would work
<sculptor> ghled - don't have a clue
<ghled> ok then
<Alipha> ghled: do: std::cout << argv[0] << std::endl; and see what's displayed. run the program from a different directory than where the program is
<ghled> right, but what if the directory is in the path?
<ghled> it would just give the program name
<ghled> getcwd doesn't do it
<Alipha> well, if you're lucky, argv[0] would be the absolute path.
<ghled> I'm not lucky
<pepp^> is there a reason why gmail and live.com won't open on ie and opera when they would open in firefox?
<Alipha> hold on a sec
<ghled> this really shouldn't be so complicated
<skie> heh. ironically, this is one of the few things I know how to do on windows but not unix.
<ghled> doesn't basically every application need to do this? like for log files
<_nx> ghled, yeah, let me think...
<ghled> ok
<skie> most things you can get away with relative paths for, first of all
<ghled> I really don't know any other way around this
<ghled> I can't since the directory could be in the user's path
<ghled> I guess I can always put it in /tmp or something like that
<ghled> but I'd rather not
<ghled> there must be some way to get the directory of the executable!
<_nx> GetModuleFileName
<ghled> this isn't Windows!
<ghled> Unix
<_nx> heh, sorry
<ghled> :(
<skie> _nx: as I said above :P
<ghled> ok, so what would you do if you had to do something like this?
<_nx> what's a unix?
<ghled> something terrible
<ghled> that gives me nightmares
<upb> getwd() or something
<ghled> getcwd gives the directory that the user is in
<skie> upb: cd /my/path/here; /path/to/exec
<upb> hrm
<skie> upb: getcwd would return /my/path/here
<sculptor> unix is something powerful
<upb> use procfs and read the link to exe :P
<skie> ghled: http://www.midnightbeach.com/jon/pubs/2002/BorCon.London/Appendix.2.html
<ghled> thanks
<ghled> waiit
<ghled> so this says I'm basically out of luck?
<skie> ghled: yeah.
<ghled> I just need some local file that my program can write to
<skie> ghled: basically, the idea of having hard links ****s everything up
<ghled> like a log file
<skie> ghled: why not get the system's /var/log directory?
<ghled> it's not a log file
<ghled> I guess I'll just write to /tmp, dammit!
<skie> then /var/*
<ghled> it's for cl*** anyway
<skie> ah.
<skie> why not use .?
<ghled> where?
<Alipha> cwd
<skie> you really should be able to just about everything with relative paths..
<ghled> right, but like I said, what if the user has the application directory in their path?
<ghled> then I would just have the program name
<ghled> without any path at all
<skie> erm
<skie> ~/appdir/myapp would still have a directory
<skie> and you can always make a subdirectory
<lordpil> 'File links are a Unix feature that has no Windows counterpart. When you create a link to a file, you're basically just adding another name for an existing inode.'
<lordpil> NT has hard links
<skie> lordpil: with much trickery
<skie> and restrictions, iirc
<skie> and that should be ntfs, not nt, strictly speaking
<skie> I've decided COM/process security is the most godawful piece of windows ever invented.
<skie> COM itself is alright. ATL makes COM somewhat pretty. security descriptors just blow chunks though.
<skie> actually, it may be tied with the registry & having UUIDs for every little goddamned thing.
<syle> anyone exp with strsep?
<ghled> skie, if I add the directory to my path, argv[0] just gives the program name
<lordpil> not really
<X-Istence> In other news today, Windows' design still ****s, Sony bundles a rootkit with their DRM CD's and the world still has not imploded!
<lordpil> it's an undocumented api
<skie> X-Istence: windows has some damn nice parts.
<X-Istence> skie: agreed. But as a programmer I have found that the not nice parts take up 90% of the time spent to fix errors.
<skie> definitely true.
<X-Istence> Whereas on other systems they are more logically done, and thus work far better
<X-Istence> and with less hackery
<skie> here's the ironic part.
<skie> read Inside Windows 2000 sometime
<skie> the actual OS is amazingly nice. its just the APIs that ****
<X-Istence> What's so ironic about that?
<X-Istence> And yes I have wanted to pick up a copy, just not had the time/money.
<skie> bug your public library to get it
<X-Istence> yaeah
<X-Istence> time for bed
<X-Istence> see ya
<pepp-> www.live.com is a joke.
<skie> heh. in theory windows would be a great OS.
<pepp-> why is microsoft doing windows live?
<skie> in practice, its aggrivating.
<pepp-> the search on msft's site, on msdn, on msn and in their windows OS are all different algos
<r0bby_> :p
<therealna> does anyone know of a guide for MS VIsual C++
<ghled> msdn must have something
<therealna> im not a subscriber
<ghled> too bad
<ghled> you shouldn't need to be
<ghled> look at their website for some tutorial
<Quant> http://www.vmware.com/support/reference/common/virtual_disks.html
<Quant> oops
<Pegazus> hi, how are you? wich are the best sorting algorithms? QuickSort in average, HeapSort and MergeSort in worst case... Radix Sort if you have higher bound... wich more?
<ghled> are you taking your midterm now?
<boxxers> hi
<boxxers> im bored.
<ghled> how can I create a file on the command line in Unix in one line
<ghled> something like cat > file without having to end the input
<lenix^> echo "abc" > file
<ghled> anyone?
<ghled> ohhh
<ghled> that's it
<ghled> I knew that
<ghled> thanks
<lenix^> no you didn't
<lenix^> hah!
<ghled> I did!
<lenix^> LOOTER!
<boxxers> lol
<boxxers> what does the %d, print ?
<boxxers> decimal?
<NoGods> If only you had documentation for printf.
<boxxers> hehe
<boxxers> i farted.
<boxxers> anyone listen to ampedout?
<MachinShi> blah. i'm bored..
<Jey> write some lisp
<MachinShi> i'd rather kill myself
<boxxers> fuu
<boxxers> im just going to write some lisp ....
<MachinShi> i'm not in a coding mood.. work drains me.. and i've not been coding enuf at work either :(
<Jasonmay> Usually I get nothing done either. But today I had two Bawls for lunch at school and I got so much done today..
<MachinShi> lol
<Jasonmay> I still can't settle down.
<ghled> what's the best way to tell if an owner has write permission to a file?
<ghled> in Unix
<Jey> open it for writing? :)
<ghled> hmmm
<MachinShi> thee's gotta be a function that gets you the permissions on a file
<Jey> sure, stat or lstat
<ghled> is opening it the easiest way, though?
Return to c++
