macosmessages
I wanted to view the manual pages for the POSIX standard message functions: msgsnd, msgrcv, etc. All of them are defined in sys/msg.h and code using them works. But the manual pages are nowhere to be found, neither in my computer (Mac OS X Mountain Lion 10.8.3), in my friends' (OS X Lion) or in the developer pages of Apple in Internet.
Where can I download that manual so I can access it right from terminal?
If you do not want (or can't) get the app out of a backup you can extract it from the installer.
Download the Airport Utility 5.6 for Lion and move the file AirPortUtility56.pkg contained within the dmg to your ~/Downloads folder. Then in a Terminal window do :
$ cd ~/Downloads
$ pkgutil --expand ./AirPortUtility56.pkg ~/Downloads/AirPortUtility56
$ gunzip -c < ./AirPortUtility56/AirPortUtility56Lion.pkg/Payload | sudo tar -C / -xvf - "./Applications/Utilities/AirPort Utility 5.6.app"
The app works without issue on Mountain Lion in my limited testing so far.
If you wanted to mod the package to skip the check, if you want to easily install the package on multiple macs for instance, here's what you need :
A tool called "Flat Package Editor" to modify the file called Distribution in AirPortUtility56.pkg. To get that tool download the "Auxiliary tools for Xcode" from the Apple Dev site. It's hidden in PackageMaker.app/Contents/resources/Flat Package Editor.app. With it you can open the pkg directly :
Just drag out the Distribution file and remove these lines :
// Less than 10.8
if(-1 != system.compareVersions(my.target.systemVersion.ProductVersion, '10.8')) {
my.result.type = 'Fatal';
my.result.message = system.localizedString('ERR_OSHIGH');
return (false);
}
Drag the new version back in, delete the old Distribution and save.
I tried all the tips imaginable. The only solution was to set the channel on the wireless router on channel 11. It seems to me, the Mountain Lion has a problem when the channel the router is in automatic, then every time the channel is changed, the connection of the Wi-Fi card of MacBook drops.

You can download them from http://manpages.ubuntu.com.
For example, to download man page
msgsnd (3):Search for
msgsndin the Google Custom Search field on the right hand side:Click on the newest man page in section 3:
Download the linked .gz man page:
Copy it to the man directory:
If you want to keep system and additional man pages apart, copy it to
/usr/local/share/man/man3/:and add:
to
/etc/profile, if you wish the new man page to be available system-wide, or~/.bash_profile, to be available to your user only (seeman man, that is,man's man page, for more information onMANPATH.)Open a new Terminal window or tab for changes to take effect.
Otherwise, copy the man page to
/usr/share/man/man3:Enjoy:
