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?
