Q_GETNEXTQUOTA(2const)                                  Q_GETNEXTQUOTA(2const)

NAME
       Q_GETNEXTQUOTA - get disk quota limits and current usage for next user
       or group

LIBRARY
       Standard C library (libc, -lc)

SYNOPSIS
       #include <sys/quota.h>

       int quotactl(QCMD(Q_GETNEXTQUOTA, type), const char *_Nullable special,
                    int id, caddr_t addr);

       #include <sys/quota.h>    /* Definition of Q_* constants */
       #include <sys/syscall.h>  /* Definition of SYS_* constants */
       #include <unistd.h>

       int syscall(SYS_quotactl_fd, int fd, QCMD(Q_GETNEXTQUOTA, type),
                   int id, struct nextdqblk *addr);

       #include <sys/quota.h>

       struct nextdqblk {
            uint64_t  dqb_bhardlimit;
            uint64_t  dqb_bsoftlimit;
            uint64_t  dqb_curspace;
            uint64_t  dqb_ihardlimit;
            uint64_t  dqb_isoftlimit;
            uint64_t  dqb_curinodes;
            uint64_t  dqb_btime;
            uint64_t  dqb_itime;

            uint32_t  dqb_valid;

            uint32_t  dqb_id;
       };

DESCRIPTION
       This operation is the same as Q_GETQUOTA(2const), but it returns quota
       information for the next ID greater than or equal to id that has a
       quota set.

       The addr argument is a pointer to a nextdqblk structure whose fields
       are as for the dqblk(2type), except for the addition of a .dqb_id field
       that is used to return the ID for which quota information is being
       returned.

RETURN VALUE
       See quotactl(2).

ERRORS
       See quotactl(2).

       ESRCH  There is no ID greater than or equal to id that has an active
              quota.

STANDARDS
       Linux.

HISTORY
       Linux 4.6.
