10.4. "statvfs" — Constants used with "os.statvfs()"
****************************************************

Deprecated since version 2.6: The "statvfs" module has been removed in
Python 3.

The "statvfs" module defines constants so interpreting the result if
"os.statvfs()", which returns a tuple, can be made without remembering
“magic numbers.”  Each of the constants defined in this module is the
*index* of the entry in the tuple returned by "os.statvfs()" that
contains the specified information.

   Preferred file system block size.

statvfs.F_FRSIZE

statvfs.F_BLOCKS

   Total number of free blocks.

statvfs.F_BAVAIL

   Free blocks available to non-super user.

statvfs.F_FILES

   Total number of file nodes.

statvfs.F_FFREE

   Total number of free file nodes.

statvfs.F_FAVAIL

   Free nodes available to non-super user.

statvfs.F_FLAG

   Flags. System dependent: see "statvfs()" man page.
