HP-UX Reference (11i v3 07/02) - 2 System Calls (vol 5)

quotactl(2) quotactl(2)

[EBUSY] Q_QUOTAON attempted while another Q_QUOTAON or

Q_QUOTAOFF is in pro-

gress.

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

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

this error is implementation-dependent.

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

[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.

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

[ENOSYS] The kernel has not been conﬁgured with the disk quota subsystem.

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

[EOPNOTSUPP] Type of quota not supported on the 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 kernel (for Q_SETQUOTA64

and Q_SETQLIM64 ).

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

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

this ﬁle system.

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.
