quotactl(4I) Ioctls for a class of drivers or subsystems quotactl(4I)
NAME
quotactl - manipulate UFS disk quotas
SYNOPSIS
#include <sys/fs/ufs_quota.h>
int ioctl(int fd, Q_QUOTACTL, struct quotcl *qp);
DESCRIPTION
This ioctl() call manipulates disk quotas on UFS filesystems. fd is the
file descriptor returned by the open() system call after opening the
quotas file (located in the root directory of the filesystem running
quotas). Q_QUOTACTL is defined in /usr/include/sys/fs/ufs_quota.h. qp
is the address of the quotctl structure which is defined as
struct quotctl {
int op;
uid_t uid;
caddr_t addr;
};
op indicates an operation to be applied to the user ID uid. (See be‐
low.) addr is the address of an optional, command specific, data struc‐
ture which is copied in or out of the system. The interpretation of
addr is given with each value of op below.
Q_QUOTAON Turn on quotas for a file system. addr points to the full
pathname of the quotas file. uid is ignored. It is recom‐
mended that uid have the value of 0. This call requires
the {PRIV_SYS_MOUNT} privilege.
Q_QUOTAOFF Turn off quotas for a file system. addr and uid are ig‐
nored. It is recommended that addr have the value of NULL
and uid have the value of 0. This call requires the
{PRIV_SYS_MOUNT} privilege.
Q_GETQUOTA Get disk quota limits and current usage for user uid.
addr is a pointer to a dqblk structure (defined in
<sys/fs/ufs_quota.h>). All users may get their own quota
information, the {PRIV_SYS_MOUNT} privilege is required
to get the quota information for another user.
Q_SETQUOTA Set disk quota limits and current usage for user uid.
addr is a pointer to a dqblk structure (defined in
sys/fs/ufs_quota.h). This call requires the
{PRIV_SYS_MOUNT} privilege.
Q_SETQLIM Set disk quota limits for user uid. addr is a pointer to
a dqblk structure (defined in sys/fs/ufs_quota.h). This
call requires the {PRIV_SYS_MOUNT} privilege.
Q_SYNC Update the on-disk copy of quota usages for this file
system. addr and uid are ignored.
Q_ALLSYNC Update the on-disk copy of quota usages for all file sys‐
tems with active quotas. addr and uid are ignored.
RETURN VALUES
This ioctl() returns:
0 on success.
−1 on failure and sets errno to indicate the error.
ERRORS
EFAULT addr is invalid.
EINVAL op is invalid.
ENOENT The quotas file specified by addr does not exist.
EPERM The call is privileged and the calling process did not assert
{PRIV_SYS_MOUNT} in the effective set.
ESRCH No disk quota is found for the indicated user. Quotas have
not been turned on for this file system.
EUSERS The quota table is full.
If op is Q_QUOTAON, ioctl() may set errno to:
EACCES The quota file pointed to by addr exists but is not a regular
file. The quota file pointed to by addr exists but is not on
the file system pointed to by special.
EIO Internal I/O error while attempting to read the quotas file
pointed to by addr.

ZFS has a different quota implementation that does not support these
ioctl calls.
