Q_XQUOTAON(2const)

NAME¶

Q_XQUOTAON - turn on quotas for an XFS filesystem

LIBRARY¶

Standard C library (libc, -lc)

SYNOPSIS¶

#include <xfs/xqm.h>      /* See quotactl(2) */
#include <sys/quota.h>

int quotactl(QCMD(Q_XQUOTAON, type), const char *_Nullable special, 0,
             caddr_t addr);

#include <xfs/xqm.h>      /* See quotactl_fd(2) */
#include <sys/syscall.h>  /* Definition of SYS_* constants */
#include <unistd.h>

int syscall(SYS_quotactl_fd, int fd, QCMD(Q_XQUOTAON, type), 0,
            unsigned int *addr);

DESCRIPTION¶

Turn on quotas for an XFS filesystem.

XFS provides the ability to turn on/off quota limit enforcement with quota accounting. Therefore, XFS expects addr to be a pointer to an unsigned int that contains a bitwise combination of the following flags (defined in <xfs/xqm.h>):

XFS_QUOTA_UDQ_ACCT  /* User quota accounting */
XFS_QUOTA_UDQ_ENFD  /* User quota limits enforcement */
XFS_QUOTA_GDQ_ACCT  /* Group quota accounting */
XFS_QUOTA_GDQ_ENFD  /* Group quota limits enforcement */
XFS_QUOTA_PDQ_ACCT  /* Project quota accounting */
XFS_QUOTA_PDQ_ENFD  /* Project quota limits enforcement */

This operation requires privilege (CAP_SYS_ADMIN).

RETURN VALUE¶

See quotactl(2).
