Possibly, but I don't know, that the man page and the app are only installed if
you also install xcode. A lot of good stuff only gets installed if you install
xcode. I know I have it in 10.5, but I have xcode installed.

Since the TCP/IP system is based on FreeBSD, you can use ifconfig to
temporarily change interface items, where you can do things like
'ifconfig alias'.
But, the configuration storage across reboots is stored in a
not-user-servicable container in darwin, and it only supports what
the graphic control panel does, so there's not much point in messing

Re: How to setup TCPIP in Mac OSX?

2009-12-21T03:04:19Z

OS X isn't BSD'ish in this regard. Though it looks that way superficially
because it makes a modicum of effort to write-out certain configurations to
/etc/resolv.conf, /etc/passwd, etc, which they expect might be needed by
some of the FOSS software they ship, in general everything is either NeXt
derived at best, or of pure OS X breeding.

You do it through their graphic Network control panel.
If you don't do it through the control panel, then it most likely won't work,
especially upon a reboot. Pretty much anything on OSX you take matters
into your own hands if you deviate from using Apple's graphic tools at all.

Re: shm_open() vs. shmget(); shm_open() vs. open()

You must mean 'ipcs'.
No way, because the sem you created via shm_open() is based
on files, no memory. Thus you can't see any related memory
segments.
Almost nothing, IMO.
In fact on Linux shm_open() are implemented as tmpfs files,
nothing particular than other regular files.

What can we do via fd1 but can't do via fd2?

In the real environment, my application communicates with external

a built-in usb-to-serial chip). The communication protocol of some of
these devices requires the use of the RTS/DTR lines. For instance the
DTR line is often used as a power supply, and the RTS line is typically
