Things Unix can do atomically

• rntz 16y ago
  Some of the things he mention have nothing to do with Unix or Posix. __sync_*, for example, are gcc-specific. Similarly, F_GETLEASE, F_SETLEASE, and F_NOTIFY are Linux-specific fcntl() operations. And as far as I can tell, the -T option isn't included in the Posix spec for mv, either (http://www.opengroup.org/onlinepubs/000095399/toc.htm http://www.opengroup.org/onlinepubs/000095399/toc.htm).

    The "POSIX spec" makes for a completely unusable UNIX, so I'm not sure why anyone would care what it says.

      Because all the world is not Linux.
      • jrockway 16y ago
        And even less of the world is POSIX.

  "UNIX-like/POSIX-compliant operating systems" So what would that not be?

    Windows. (And don't even mention Windows POSIX.)
