Q_XQUOTARM(2const)                                          Q_XQUOTARM(2const)

NAME
       Q_XQUOTARM - free disk space taken by disk quotas

LIBRARY
       Standard C library (libc, -lc)

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

       int quotactl(QCMD(Q_XQUOTARM, 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_XQUOTARM, type), 0,
                   unsigned int *addr);

DESCRIPTION
       Free the disk space taken by disk quotas.

       The addr argument should be a pointer to an unsigned int value
       containing flags (the same as in .d_flags field of the
       fs_disk_quota(2type) structure) which identify what types of quota
       should be removed.

       Quotas must have already been turned off.

RETURN VALUE
       See quotactl(2).

ERRORS
       See quotactl(2).

       EINVAL (since Linux 5.5)
              addr does not point to valid quota types.

STANDARDS
       Linux.

HISTORY
       Buggy until Linux 3.16.

CAVEATS
       The quota type argument is ignored, but should remain valid in order to
       pass preliminary quotactl syscall handler checks.
