-/****************************************************************************
-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!
