HP-UX Reference (11i v2 07/12) - 2 System Calls (vol 5)

quotactl(2) quotactl(2)

[EINVAL] The parameters cmd and/or uid are invalid.

[ESRCH] No disc quota is found for the indicated user or quotas have not been turned on for

this ﬁle system.

[EPERM] The call is privileged and the calling process does not have appropriate privileges.

[ENODEV] The parameter special contains a type of ﬁle system that does not support quotas.

Currently, quotas are supported on HFS and VxFS ﬁle systems.

[ENOTBLK] The parameter special is not a block device.

[EACCES] (

Q_QUOTAON) The quota ﬁle pointed to by addr exists but is either not a regular ﬁle

or is not on the ﬁle system pointed to by special.

[EBUSY]

Q_QUOTAON attempted while another Q_QUOTAON or Q_QUOTAOFF

is in pro-

gress.

[ENOENT] The ﬁle speciﬁed by special or addr does not exist.

[EFAULT] The addr or special parameter points to an invalid address. Reliable detection of this

error is implementation-dependent.

[EDQUOT] User’s disk quota block limit has been reached for this ﬁle system.

[EOVERFLOW]

64-bit values will overﬂow 32-bit ﬁelds, either in the

dqblk struct in the user level

(for Q_GETQUOTA) or in a 32-bit ﬁle system in the kernal (for Q_SETQUOTA64 and

Q_SETQLIM64 ).

WARNINGS

The quotactl() system call is incompatible with the 4.2/4.3 BSD implementation of Melbourne quotas

which uses a different system call interface and on-disk data structure.

Use Q_GETQUOTA64 , Q_SETQUOTA64 , and Q_SETQLIM64 commands for 64-bit ﬁeld values.
