/****************************************************************************
|
|
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!
