## DESCRIPTION

- *.dqb\_bhardlimit* *.dqb\_bsoftlimit*

  Absolute and preferred limits on disk quota blocks.

- *.dqb\_curspace*

  Current occupied space (in bytes).

- *.dqb\_ihardlimit* *.dqb\_isoftlimit*

  Absolute and preferred limits on number of allocated inodes.

- *.dqb\_curinodes*

  Current number of allocated inodes.

- *.dqb\_btime*

  Time limit for excessive disk use.

- *.dqb\_itime*

  Time limit for excessive files.

- *.dqb\_valid*

  Bit mask of **QIF\_***\** constants. It is set to indicate which fields in the *dqblk* structure are valid.
