    Hi

    I haven't found the entry point, which is invoked on mmap/shmat call.

    In Linux and in Solaris I use mmap to map the special file to memory.
    I know that in AIX shmat works with character devices and mmap with block devices.

    I wonder how a block/character device accepts mmap/shmat call.

    Thanks
