+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.
-#elif defined(SUNOS5) || defined(SUNOS4)
+ My guess is that Veritas is largely, though not entirely,
+ independent of OS. So I have separated it out.
-#include <fcntl.h>
+ 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!
