The socket will be used only briefly but the server is going to keep running. Really... this piece of code isn't set up to be launched in this manner. Maybe I should just keep what I have and launch it at boot time and be happy. But, if I continue on: I'm looking at launch.h and reading. I was toying with an idea of writing a program, call it "get_sockets". The script would run get_sockets and get_sockets would print on stdout something that could be easily parsed. Like the key for each socket and then the fd number for that key. I'm making great leaps of assumptions here on what the launch_data is going to look like so I may be way off base. Given that you're using a scripting language, your best option is to leverage launchd's inetd compatibility. By doing so, you'll get automatic concurrency (at the cost of inefficiency) and implicit compatibility with other operating systems that supply [x]inetd. Assuming that your program is TCP based, then this should be sufficient: Once you make that change, you'll find the socket on stdin/stdout/ stderr at launch. This question has come up for me before and I suspect it will again. The example this time is the web "server" that serves the Ruby "rdoc" documentation. You start it with "gem server". It has a few options like which port which has a default. I have a launchd plist file that simply starts this up at boot. But, mostly so I can show off to my friends (if I had any :-), I'd like to start it up the first time I browse to that port. The man page for launchd.plist says that the process has to "check in" using the launch(3) API. "man 3 launch" gives me back nothing. So I am lost as to what API's there are. But, even if I could find them, thats really just half the problem. The real problem is I'm looking for a way to transfer the file descriptor from launchd to the gem server using a script. (I can't modify gem just to do this -- well, I suppose I could but that only defers the problem until next time this comes up). So, how is this done? Or... if I need to write some code, thats fine. But, where do I start? _______________________________________________ Do not post admin requests to the list. They will be ignored.

Sun RPC in OSX

Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… I am porting some windows code which makes use of the "oncrpc" Sun-RPC lib (librpc, rpcgen XDR etc) I do have the RPC source code of the libraries originally linked to the actual application code I am porting, but its from the late 90's and there is alot of it. My question is whether OSX includes the sun librpc - I did find some of the same stuff in the Mac OSX development kit, but its not clear if this is the same, or something slightly different, or a subset. I can see that documentation that Apple supports XML-RPC via Apple events, but this seems to be different to the original RPC I am dealing with (which is not the XML type).

On the other hand when I try accessing the server, from my Intel machine, using the IPv6 address specifed by the en0 interface I can't connect: I guess the reason is the library used on darwin is too old one to handle scope id. The library, specifically getaddrinfo(3), on other BSDs can handle scope id followed scope id delimiter('%'). There is no work around for your purpose other than using global IPv6 address. in case of ping6, you can use '-I' option to specify the scope (interface).

I mistakenly mistook "FileVault" for "Time Machine" so please ignore my previous post WRT FileVault. (For Time Machine my comments would still be valid though ;-) Unfortunatly I don't know about any general way of checking for FileVault volumes. One thing though: on Tiger the mountpoint for the FileVault volume is not /Volumes/<name> but /Users/<name>. (I havn't checked Leopard yet but I suspect the same.) So finding the Volume in the first place might not be obvious. The permissions for mounted FileVault volumes, or rather /Users/ <name>, differ from those for normal users. While not a sure fire way this might be a hint. This email sent to site_archiver(a)lists.apple.com

I'm not sure what you are expecting to happen then. diskutil unmountdisk disk1 will unmount the disk and all of it's volumes. You can then safely remove the disk. If all of the volumes do not unmount then there is a file open on that volume and the disk cannot be safely unmounted. USB drives and FireWire drives are slightly different with unmountdisk. USB will/should unmount and be gone from the system. In order to remount you have to remove the cable and replug the cable. FireWire drives stay in the system and can be remounted. This has been my experience primarily with USB flash drives. I haven't tried USB hard drives in a long while so I don't recall if they work the same way. >Can you >give me some code reference for this DiskArbitration to proceed. #include <DiskArbitration/DiskArbitration.h> There is minimal documentation but if you Google a bit, you can find some examples. >On Jan 18, 2008 11:28 AM, Duane Murphy <duanemurphy(a)mac.com> wrote: >--- At Fri, 18 Jan 2008 11:18:24 +0530, Elango C wrote: > >>Hello, >> >>I am currently trying to eject the USB Drive by writing a small >>carbon application.
