And I should also point out that I want to run the *client* (the server is always available on another machine), which can be run as a daemon by passing the --daemon option. Can this really be made to work "on demand"? My initial idea was to build a preference pane to turn the connection on and off. But, for some reason, I cannot make openvpn start up correctly from code. In some more tests I have made, I have noticed a "route: must be root to alter routing table" error when my (authenticated) tool launches openvpn - which baffled me, because the command is supposed to be executed with root privileges (I have verified that uid = 501, euid = 0). I like, however, "Apple's idealized view", if only I could implement it. Where may I find more information: man pages only? 2) Is launchd to be preferred over other methods in this case? And is it the way to go in general? The preferred solution does not involve launchctl or programmatic control whatsoever. In Apple's idealized view of the universe, your VPN daemon would be launch on demand via some IPC based mechanism. This has the nice side effect of implicit correctness. From your client's perspective, the daemon is virtually running all the time. davez This email sent to site_archiver(a)lists.apple.com

How to do a blocking read from a serial device?
by Sean McBride 10 Jul '06

10 Jul '06

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com Organization: Rogue Research Hi all, I am writing some code to work with an RS-232 serial device (via USB adapter). It basically works. All the IOKit parts are fine, and I end up with a file descriptor and then use the posix read() and write() APIs. The read() man page says "The system guarantees to read the number of bytes requested if the descriptor references a normal file that has that many bytes left before the end-of-file, but in no other case." Indeed with my serial device, if I say to read 15 bytes it sometimes returns after reading 10 bytes. Is there anyway to have read() block until the requested length is ready? Is my only other choice some kind of loop that calls read() and usleep() over and over? If so, how do I choose a sleep duration? Thanks! -- ____________________________________________________________ Sean McBride, B.
