/****************************************************************************
Try to get the disk space from Veritas disk quotas.
    David Lee <T.D.Lee@durham.ac.uk> August 1999.

Background assumptions:
    Potentially under many Operating Systems.  Initially Solaris 2.

    My guess is that Veritas is largely, though not entirely,
    independent of OS.  So I have separated it out.

    There may be some details.  For example, OS-specific "include" files.

    It is understood that HPUX 10 somehow gets Veritas quotas without
    any special effort; if so, this routine need not be compiled in.
        Dirk De Wachter <Dirk.DeWachter@rug.ac.be>

Warning:
    It is understood that Veritas do not publicly support this ioctl interface.
    Rather their preference would be for the user (us) to call the native
    OS and then for the OS itself to call through to the VxFS filesystem.
    Presumably HPUX 10, see above, does this.

Hints for porting:
    Add your OS to "IFLIST" below.
    Get it to compile successfully:
        Almost certainly "include"s require attention: see SUNOS5.
    In the main code above, arrange for it to be called: see SUNOS5.
    Test!
