I'm studying a book on UNIX programming and in the SysV IPC chapter
the book states that these interfaces will soon be obsoleted by
improved Posix interfaces to solve the same IPC problems. I tried
finding info on this and all I came up with was that Posix.1b now
incorporates these calls and that shared memory is implemented as
mmap() in Posix.1b. Are these the only changes? What about semaphores
and message queues? Do these "new" Posix calls use file descriptors or
are they still non-UNIX-oriented as the SysV calls?
